    • Vinyl phenols, e.g. ortho, meta, and paravinyl phenols, and their methyl, ethyl, and propyl nuclear derivatives, are copolymerized with unsaturated alkyd resins derived from alpha, beta unsaturated polycarboxylic acids, the vinyl phenol constituting from 0.1 to 99.9 per cent of the monomer mixture. The unsaturated alkyd resins, which may be used in either the monomeric or partially polymerized state, are derived from polyhydric alcohols such as glycol, diethylene glycol, propylene glycol, butylene glycol, hexamethylene glycol, glycerol, pentaerythritol and their mixtures, and acids such as maleic, fumaric, itaconic, mesaconic, citraconic acids, or their anhydrides, or mixtures thereof. The alkyd resins may be prepared in the presence of zinc chloride and modifying agents such as butanol, decyl and octadecyl alcohols, phthalic, succinic, sebacic, butyric, stearic and abietic acids or anhydrides, castor oil, dehydrated castor oil and tung oil. Copolymerization may be carried out in bulk or aqueous dispersion, when the pH is preferably maintained below 7, with the aid of heat, actinic light, and catalysts such as lauryl, acetyl, crotonyl, benzoyl, tert.-butyl, and isopropyl benzene peroxides, tert.-butyl and isopropyl benzene hydroperoxides, hydrogen peroxide, alkali metal and ammonium persulphates and perborates, Friedel-Crafts catalysts, stannic chloride, hydrochloric and sulphuric acids, and acid-activated clays. The reaction may be terminated at a point short of gelation, and the copolymers stabilized by the addition of hydroquinone or metol. Hardening may be effected subsequently after the removal of the inhibitor, addition of more catalyst, or further heating. The copolymers may be used as a basis for moulding compositions, as rubbery sheets, and in the production of laminates and lacquers. Specification 691,037 is referred to.

    • Oil-modified alkyd resins are prepared by heating a mixture of castor oil, a polyhydric alcohol and a polybasic acid or anhydride thereof at a temperature between 260 DEG and 270 DEG C. until the initial decrease in viscosity of the reaction mixture has substantially ceased, and, before there is any substantial increase in viscosity adding a sufficient quantity of polyhydric alcohol and/or polybasic acid or anhydride thereof at such a temperature as to reduce the temperature of the reaction mixture to a value not exceeding 230 DEG C., and continuing to react the added polyhydric alcohol and added polybasic acid or anhydride thereof at a temperature between 160 DEG and 230 DEG C. and adding any further polyhydric alcohol and/or polybasic acid or anhydride which may be necessary to produce a reaction product, the oil content of which does not exceed 50 per cent thereof and which contains a small amount of free polyhydric alcohol. Cooling means may be provided to remove the excess heat of the reaction vessel. Preferably, the initial reaction mixture contains 5-75 per cent excess of glycerol over the equivalent amount and contains 40-95 per cent of oil. Any further additions of polyhydric alcohol are preferably made before the addition of further polybasic-acid. Suitable alcohols are glycerol, pentaery, thritol, ethylene glycol, trimethylol propane mannitol, sorbitol and butyne-diol, and suitable acids are phthalic acid and anhydride, tetrahydrophthalic acid, tetrachlorophthalic anhydride, methylene di-salicylic acid, maleic, fumaric and citric acids, and maleic and fumaric acid adducts with terpenes and cyclo-olefines. In examples, castor oil, glycerol and phthalic anhydride are heated at 260-270 DEG C., and when the minimum viscosity is passed sufficient glycerol is added to reduce the temperature to 230 DEG C. Further phthalic anhydride is added, followed by further heating, firstly at 230 DEG C. and then at 180 DEG C.; (2) the procedure of (1) is followed, but a further addition of phthalic anhydride and glycerol is made whilst heating at 180 DEG C.; (3) castor oil, phthalic anhydride and glycerol are heated at 260-270 DEG C. and pentaerythritol added when the minimum viscosity is passed to reduce the temperature to 230 DEG C. Phthalic acid is added and heating continued at 220 DEG C.; (4) sorbitol replaces the pentaerythritol of (3). The products dissolved in xylene are p suitable as varnishes, and cobalt linoleate or naphthenate driers may be added. Specifications 431,495 and 474,620 are referred to. A sample has been furnished under Sect. 2 (5) of a product obtained by heating castor oil glycerol and phthalic anhydride, and when the minimum viscosity is reached adding more glycerol and phthalic anhydride and heating at 220 DEG C., then adding butyne diol and heating at 210 DEG C. The product at 200 DEG C. is dissolved in xylene.

    • Aryl substituted silicanes of the general formula RnSi(OR1)4-n, wherein R represents an aryl residue, R1 is a secondary alcohol residue containing more than three carbon atoms and n is a whole number less than 4, are prepared by reacting a silicane of the general formula XnSi(OR1)4-n, wherein R1 and n have the above significance and X represents halogen, with a mono-halogenated aryl hydrocarbon in the presence of an alkali metal, e.g. sodium. The reaction may be carried out in stages by first reacting the mono-halogenated aryl hydrocarbon with the alkali metal, and then reacting the resulting alkali metal aryl with the halogeno-silicane. The reaction may be effected under the usual conditions for a Würtz-Fittig reaction, in the presence or absence of diluents, e.g. ether, petroleum ether or other inert solvents, and in the presence or absence of catalysts, e.g. ethyl alcohol, acetic acid and ethyl acetate. The aryl substituted silicanes may be hydrolysed to yield silicols of the general formula RnSi(OH)4-n, wherein R and n have the above significance, e.g. by heating with aqueous alkalis or aqueous acids in the presence of a water-miscible solvent for the silicanes such as the monethyl ether of ethylene glycol. In examples: (1) to (4) phenyl-tricyclohexoxysilicane is prepared by reacting chlorobenzene, sodium and chloro-tricyclohexoxy silicane; (5) and (6) diphenyl-dicyclohexoxy-silicane and diphenyl - di - secondary - butoxy - silicane are prepared by reacting sodium, chlorobenzene and dichloro-dicyclohexoxysilicane and dichloro - di - secondary - butoxysilicane respectively; (7) phenylsilicanetriol is prepared by hydrolysing phenyl-tricyclohexoxysilicane prepared as in examples (1) to (4).

    • A synthetic resin is prepared by heating an alkyd resin, which may be oil-modified or not, with the hydrolysis product of a compound of the formula RnSiX4-n, where R represents any substituted or unsubstituted hydrocarbon radical such as alkyl, e.g. methyl, ethyl, propyl, n- or i-butyl; cycloalkyl, e.g. cyclohexyl; aryl, e.g. phenyl, para-chlorphenyl and para-tolyl; or aralkyl, e.g. benzyl; X is a halogen, e.g. chlorine, bromine or iodine, or OR1- (where R1 is a hydrocarbon radical), e.g. methoxy, ethoxy, or phenoxy; and n is a whole number less than 3. Specified compounds of the above formula are methylsilicon trichloride, dimethylsilicon dichloride, diphenylsilicon dibromide, phenylethylsilicon dichloride, phenylsilicon trichloride, dibenzyl silicon dichloride, phenyltriethoxy silicane, diphenyldiethoxy silicane, cyclohexylsilicon trichloride and para-tolylsilicon trichloride. The alkyd resins may be glyceryl phthalates modified or not with linseed oil, castor oil or hydrogenated castor oil. The reaction is preferably carried out in a solvent, e.g. benzene, toluene, xylene or n-butanol. The product, dissolved in a solvent, e.g. butanol, with or without the incorporation of pigments, e.g. titanium dioxide, may be used as a coating composition. In examples: (1) castor-oil-modified glyceryl phthalate resin is reacted in xylene solution with the hydrolysis product of phenylsilicon trichloride and the product is dissolved in butanol; with the addition of titanium dioxide and xylene, an enamel is formed; (3) hydrogenated-castor-oil-modified glyceryl phthalate resin is reacted in xylene solution with the hydrolysis product of phenylsilicon trichloride; the product dissolved in butanol and titanium dioxide added to form a coating composition; (4) linseed-oil-modified glyceryl phthalate resin is reacted with the hydrolysis product of phenylsilicon trichloride in xylene solution, the product dissolved in butanol and xylene and pigmented with titanium dioxide forming a coating composition to which cobalt naphthenate may be added; (5) butanol-modified glyceryl adipate resin is reacted with the hydrolysis product of phenylsilicon trichloride in xylene solution, the product dissolved in butanol and xylene, and pigmented with titanium dioxide to form a coating composition; (6) castor-oil-modified glyceryl phthalate resin is reacted with the hydrolysis product of benzylsilicon trichloride in xylene solution and the product dissolved in butanol; (7) castor-oil-modified glycerylphthalate resin is reacted with the hydrolysis product of cyclohexyl silicon trichloride in xylene solution and the product is dissolved in butanol; (8) castor-oil-modified glycerylphthalate resin is reacted with xylene solution with the hydrolysis product of the reaction production of methyl magnesium chloride with silicon tetrachloride and butanol is added periodically when the mixture gels and the product is finally dissolved in butanol. The compounds formulated above may be obtained by treatment of the appropriate tetrahalogenosilicane or silicic acid ortho-ester with Grignard reagents, and may be hydrolysed by treatment with water, aqueous alkali or aqueous acid. In an example, phenylsilicon trichloride dissolved in ether is added slowly to ice-water with cooling. The ether layer, together with an ether extract of the aqueous layer, is washed with water, dried, and mixed with xylene and the ether evaporated.

    • Vinyl phenols or their lower nuclear homologues, e.g. methyl, ethyl or propyl substituted derivatives, are copolymerized with styrene compounds, e.g. styrene, monomethyl, ethyl and a -methyl p-methyl styrene and mono- and dichlorstyrenes; maleic acid esters and half esters of saturated aliphatic alcohols; acrylic compounds, e.g. methacrylic, a -ethyl, a -chlor, a -fluor acrylic acids, methyl and ethyl acrylates, ethyl and butyl methacrylates, methyl a -chlor-acrylate, acrylonitrile, methacrylonitrile, acrylyl chloride, and acryl- and methacrylamide; vinyl organic esters, e.g. formate, acetate, propionate, butyrate and stearate; vinyl ethers, e.g. methyl, ethyl, isopropyl, butyl, phenyl, tolyl, naphthyl, vinyl and propenyl ethers; vinyl ketones, e.g. methyl, ethyl, isopropyl, and butyl ketones; N-vinyl compounds, e.g. N-vinyl carbazole, pyrrole and piperidine; polymerizable allyl compounds, e.g. esters of allyl, methallyl, ethallyl, chlorallyl, crotonyl, cinnamyl, butene-1-ol-3, pentene-1-ol-3 and butadiene-2 : 3-ol-1, and polyhydric allyl alcohols with formic, phenoxy formic, acetic, lactic, butyric, glycollic, salicylic and oleic acids; or allyl ethers and allyl substituted aldehydes and ketones and their acetals and ketals. The reactive group in the latter may be chemically after-treated, and the vinyl ester copolymers may be hydrolysed partially or completely to produce vinyl alcohol units which in turn may be acetalized, e.g. with formaldehyde or hexamethylene tetramine. Copolymerization may be effected by heat or ultra-violet light with catalysts such as acetyl, crotonyl, benzoyl, tertiary-butyl, and isopropyl benzene peroxides, tertiary butyl perbenzoate, tertiary butyl and isopropyl benzene hydroperoxides, hydrogen peroxide, alkali metal or ammonium persulphates, Friedel-Craft catalysts, such as boron tri-fluoride, strong hydrochloric or sulphuric acid and acid-activated clay, or a Redox system with, e.g. sodium sulphite, in a homogeneous phase or in an aqueous dispersion of pH 7 or less. High molecular weight polymers may be separated by dissolving the initial resin in benzene, for example, and fractionally precipitating by an ethanol/petroleum ether mixture. The resins may be after-treated by cross-linking and/or etherification. Examples describe the homogeneous copolymerization of meta-vinyl phenol with styrene, ethyl acrylate, allyl caproate, diamyl maleate, ethyl vinyl ether containing divinyl ether, diallyl phthalate, and N-vinyl carbazole; of orthovinyl phenol with styrene; the copolymerization of meta-vinyl phenol with acrylonitrile, vinyl acetate or styrene in emulsions, in which sulphonated castor oil, polyethylene oxide, sodium sulphite and hydrogen peroxide are used; and the copolymerization of a solution of b -methyl styrene and m-vinyl phenol in toluene.

    • Polymers and copolymers of ortho and meta vinyl phenols and their lower nuclear homologues are etherified by reaction with an unsaturated or saturated alkyl inorganic ester, e.g. dimethyl or diethyl sulphate, allyl or b -methallyl chloride, bromide or iodide but not fluoride. Copolymers with compounds such as butadiene hydrocarbons, chloroprene, styrene compounds, vinyl naphthalenes, acenaphthylene, N-vinyl pyridine, cyclopentadiene, vinyl and vinylidene halides, vinyl esters, acrylic esters, acrolein, or allyl compounds may be used. The polymer may be treated in a solution or dispersion in an alkaline polar medium, e.g. water or lower aliphatic alcohol or a non-polar medium, e.g. benzene or benzene-alcohol mixture, and in the latter case a quaternary ammonium hydroxide condensing agent is preferable. Films formed from a solution of the product in benzene containing tert-butyl hydroperoxide may be rendered insoluble on heating. In a modification the polymeric resin is treated with both an aldehyde and an etherifying agent, together or separately in one or two stages to yield a thermosetting resin which may be used as a moulding powder when compounded with fillers, plasticizers and lubricants, or used as a lacquer or adhesive when in a solution or dispersion. In examples poly-m-vinyl phenol, copolymers of m-vinyl phenol with styrene or methyl acrylate, and of o-vinyl phenol with styrene are etherified, the alkaline agents used being sodium hydroxide, methyl pyridinium hydroxide and tetramethyl ammonium hydroxide; and poly-m-vinyl phenol is reacted simultaneously with dimethyl sulphate and formaldehyde.
