摘要： The invention comprises compounds of the formula where n and a are each 0 or 1, R is a monovalent hydrocarbon or halogenated hydrocarbon radical, and R1 is an alkylene or arylene group. They are prepared by the reaction of tetraphenyl disiloxane diol-1,3 or hexaphenyl trisiloxane diol-1,5 with the appropriate nitrile-containing organo dihalosilane Ra(R1CN)2-aSiX2, where X is halogen in an inert solvent in the presence of a hydrogen halide acceptor, e.g. a tertiary amine, in particular pyridine. The hydrohalide precipitate is removed, then the solvent, and the product is recrystallized. Polymers containing the recurrent unit where n, a, R and R1 are as defined above, are prepared by heating the compounds (I) alone at 300-375 DEG C., or, preferably, with a catalyst at 110-170 DEG C. A suitable catalyst is a 0.01-1% solution of KOH in octamethyl cyclotetrasiloxane, amounting to 10-100 p.p.m. of KOH in the monomer. The polymers have M.W.'s of 10,000 to 5,000,000, and are soluble in benzene or toluene. In the same way copolymers can be made from mixtures of compounds (I) with themselves or other cyclic polysiloxanes or cyclic siloxane-silphenylenes, e.g. those of Specifications 980,101, 980,102, 980,103, 980,104, 980,105, 980,106, 980,107 and 980,109. Homopolymers of units (II) are best cross-linked by irradiation, e.g. with 50,000-20,000,000 eV electrons, and copolymers containing vinyl groups or adjacent methyl groups may be cured by irradiation or by conventional free radical (e.g. peroxide) curing agents. Fillers may be added before cure, if required, and may suitably be silica (aerogel, fumed, precipitated), glass fibres, TiO2, Fe2O3, Cr2O3, CaCO3, CaSiO3, CdS, lithopone, carbon black, asbestos, talc, &c. The examples describe the preparation and polymerization of 1-methyl-1 - b - cyanoethyl - 3,3,5,5 - tetraphenyl cyclotrisiloxane, 1 - methyl - 1 - m - cyanophenyl - hexaphenyl cyclotetrasiloxane and 1,1-bis-(b - cyanoethyl) 3,3,5,5 - tetraphenyl cyclotrisiloxane, and the preparation of g -cyano-propyl - heptaphenyl cyclotetrasiloxane and its copolymerization with hexaphenyl cyclotrisiloxane, and the cure of the polymers by irradiation.

摘要： The invention comprises compounds of the formula where n is 0 or 1. They are prepared by the reaction of tetraphenyl disiloxane diol-1,3 or hexaphenyl trisiloxane diol-1,5 with a methyl phenyl dihalosilane in an inert solvent in the presence of a hydrogen halide acceptor e.g. a tertiary amine, in particular pyridine. The hydrohalide precipitate is removed, then the solvent, and the product is recrystallized. Polymers containing the recurrent unit where n is 0 or 1, are prepared by heating the compounds (I) alone at 250-350 DEG C., or, preferably, with a catalyst at 110-170 DEG C. A suitable catalyst is a 0.01-1% solution of KOH in octamethyl cyclotetrasiloxane, amounting to 10-100 p.p.m. of KOH in the monomer. The polymers have M.W.'s of 10,000 to 5,000,000 and are soluble in benzene and toluene. Copolymers can be made in the same way from mixtures of compounds (I) with themselves or other cyclopolysiloxanes, which may contain halohydrocarbon, alkenyl or cyanoalkyl radicals, or with cyclosiloxanesilphenylenes, e.g. those of Specifications 980,101, 980,102, 980,103, 980,104, 980,105, 980,106, 980,108 and 980,109.

Fillers may be added before cure, if required, and may suitably be silica (aerogel, fumed, precipitated), TiO2, FeO3, Cr2O3, CaCO3, CaSiO3, CdS, lithopone, asbestos, talc, glass fibres or carbon black. Examples describe the preparation, polymerization and cure to a silicone rubber of each of the compounds (I), and the copolymerization of the tetrasiloxane (I) with octaphenylcyclotetrasiloxane and the cure of the product.

摘要： A process for introducing N-bonded-ester groups into polyalkylene-polyamino-silicon compounds comprises reacting (A) an alkyl-acrylate or methacrylate wherein the alkyl radicals contain less than 5 carbon atoms, with (B) an organo-silicon compound containing at least one monovalent substituent of the general formula bonded to silicon by C-Si bonding, wherein each R11 is an alkyl radical containing 1 to 4 carbon atoms or a hydrogen atom, at least one R11 being a hydrogen atom, x is 0 to 10, y is 1 or 2, R1 is a hydrocarbon radical containing 1 to 18 carbon atoms and of valency (y+1). (B) may be either (a) an organosilane of general formula wherein each R is an alkoxy radical, hydrogen atom or a hydrocarbon radical free from aliphatic unsaturation and containing 1 to 18 carbon atoms, or a halogenoaryl radical, or (b) a siloxane of unit general formula (I) wherein m is 0 to 3. Radicals R1 are represented by the general formula CmH2m= or CmH2m- 1, where m is 1 to 18, and may be branched or linear. Siloxane polymers may be homopolymers of Formula (I) or copolymers containing up to 99 mole per cent of units of formula where m is 0 to 3 and Z is a monovalent hydrocarbon or halogenoaryl radical or hydrogen. The reaction may be optionally carried out in an inert solvent. Higher alkyl acrylates and methacrylates may require an elevated temperature. Preferred quantities or reactants are 1 to 5 moles of acrylate per molar equivalent of polyalkeneamine group in the organo-silicon reactant. The examples describe the preparation of, inter alia, the following:-(1) and (3) (CH3O)3Si-(-CH2-) -3-(NHCH2CH2-2CO2CH3, (3) (CH3O)3Si-(-CH2-) -3NHCH2CH2-N(CH2CH2COOCH3) 2, (7) CH3OOC-(-CH2-CH2-NH-) -2CH2CH-(CH3)CH2-[-Si(CH3) 2O-] -6Si(CH3)2-CH2-CH(CH3) -CH2-(-NH-CH2-CH2-) -2CO2CH3 and (8) a polymer of unit formula CH3OOC-(-CH2-CH2NH-)2 -CH2CH(CH3)-CH2Si(CH3)O. Uses.-For binding pigments to glass fabric and other silicaceous surfaces; priming agents on metal surfaces prior to coating with resin; binding agents in the preparation of glass-fibre polyester laminates; preparing silicon elastomers; heat exchange agents.

摘要： The invention comprises organosilicon compounds, which cure on exposure to moisture, of the formula wherein a is 2-4, b is 0-1, R is a divalent radical free from aliphatic unsaturation, consisting of hydrocarbon radicals or radicals containing C, H and O and/or S in the form of C-O-C, -OH, -SH or C-S-C, c is at least 1, R1 is a multivalent hydrocarbon radical or a radical containing C, H and O in the form of C-O-C or C-OH, there being no acetylenic unsaturation in R1, R11 is a monovalent hydrocarbon radical or a halohydrocarbon radical, n is 0-2, X is a hydrolysable group or atom, m is one less than the valency of R1; there being an average of at least 2 Si atoms and 3X groups in each molecule. The preferred value of C is 5-100. X is preferably acyloxy, alkoxy or hydrocarbyl-substituted isocyanoxy. The compounds may be prepared (I) by reacting polysulphide polymers of the formula HS[CH2(R)bCH2Sa]cCH2(R)b CH2SH with a silane containing a substituent having the C=C group in the presence of peroxides or an alkaline catalyst, (2) by reacting the sodium salt of the polysulphide polymer with a silane having a halogen atom on an organic substituent, (3) by reacting a polysulphide polymer with an epoxy silane. The compounds may be stored without curing if they are kept anhydrous, even in the presence of curing catalysts. The compounds are cured on contact with water, preferably in the presence of catalysts such as alkyl titanates, metal salts of carboxylic acids, amines, amine salts of carboxylic acids and quaternary ammonium compounds. "Pigment," including structural fillers and extending fillers, may be added to the polymers, e.g. carbon blacks, silicas, TiO2, ZnO, lithopone and clay.
