摘要： Threads, fibres and films are produced by spinning solns. of (mod)acrylonitrile polymers contg. 0.05-4.0 wt.% based on polymer, cyanethylated phosphine of formula (I) opt together with 0.01-0.1 wt. % tris-(oxymethyl)-phosphine. R - P (CH2 - CH2 - CN)2 (I) (where R is H, alkyl, or CH2CH2CN). Pref. (I) is tris-(2-cyanoethyl)-, bis-(2-cyanoethyl)-, or n-hexyl- bis-(2-cyanoethyl)-phospine. The phosphine are added to the solvent before the polymer. Prevents discolouration of the spinning solns. at high temps. The stabilisers have a low toxicity, and are non-irritating to the skin.

摘要： 1327530 Isobutyl methacrylate copolymers; paint binder compositions ROHM GmbH 9 Dec 1971 [9 Dec 1970] 57344/71 Heading C3P Copolymers suitable for use as binders in airdrying paints comprise units of (a) 60-95% by weight of isobutyl methacrylate, (b) 3-30% by weight of an ester of acrylic acid with a C 6- C 12 alcohol, (c) 1-10% by weight of a mono- or poly-hydroxyalkyl ester or mono- or polyhydroxyalkyl amide of acrylic and/or methacrylic acid containing at least two carbon atoms in the hydroxyalkyl group, the said hydroxy group(s) not being bonded to the α-carbon atom of the hydroxy alkyl group, and optionally (d) up to 12% by weight of one or more other comonomers. Examples of component (b) are the n-hexyl, n-octyl, n-decyl, n-dodecyl and 2-ethylhexyl acrylates. Suitable as component (c) are #-hydroxy ethyl and #-hydroxy propyl (meth) acrylate, 8-hydroxy butyl acrylate, 2,3- dihydroxy propyl methacrylate, and #-hydroxy ethyl- or #-hydroxyl propyl-(meth) acrylamide. Optional monomers (d) include acrylate esters of C 1 -C 4 alcohols, methacrylate esters, styrene and vinyl toluene. The copolymers can be prepared by polymerizing the monomers in solution (e.g. in petroleum distillate) or preferably in an aqueous medium (containing e.g. magnesium carbonate dispersing agent and sodium alkylsulphonate suspension stabilizer) to produce a bead polymer; a modifier such as dodecyl mercaptan may be present and the polymerization initiated with, e.g., dilauroyl peroxide. For coating purposes, the copolymers are suitably dissolved in a solvent such as petroleum distillate, and a pigment, e.g. titanium dioxide, and optionally a filler, e.g. a mixture of dolomite and silicate materials, added. A soft resin such as a polyalkyl (C 4 -C 6 ) acrylate or a plasticizer such as a chloroparaffin may also be included.

AN ACRYLIC POLYMER WHICH COMPRISES A GRAFT COPOLYMER HAVING THE GENERAL STRUCTURE A-B where A is the backbone segment and B is the graft segment; the acrylic polymer is formed by polymerizing the following monomer units to form the backbone segment A methylmethacrylate, an alkyl methacrylate or an alkylacrylate, a hydroxalkylacrylate or methacrylate, a polymerizable carboxylic acid such as acrylic acid or methacrylic acid, and a grafting site monomer such as allymethacrylate to which a side chain segment B is grafted of acrylamide or methacrylamide and optionally a hydroxyalkylacrylate or a hydroxyalkylmethacrylate; 2. A LINEAR ACRYLIC POLYMER OF METHYL METHACRYLATE, AN ALKYL ACRYLATE OR AN ALKYL METHACRYATE, A HYDROXYALKYL ACRYLATE OR A HYDROXYALKYL METHACRYLATE, AND AN ETHYLENICALLY UNSATURATED CARBOXYLIC ACID WHICH IS 75-100 PERCENT NEUTRALIZED WITH AMMONIA OR AN AMINE; AND 3. A WATER-DISPERSIBLE CROSS-LINKING RESIN SUCH AS HEXAKIS(METHOXYMETHYL) MELAMINE; THE NOVEL COATING COMPOSITION FORMS A HIGH QUALITY FINISH FOR AUTOMOBILE AND TRUCK BODIES AND ALSO CAN BE UTILIZED FOR APPLIANCES SUCH AS REFRIGERATORS AND STOVES AND FOR CABINETS AND THE LIKE.
