Abstract: Aq. polyesterimide dispersions, contg. polyesterimide as fine solid particles, having particle sizes 5 mu, are prepd. by (1) precipitating an opt. esterification catalyst-contg. soln. of a polyesterimide precondensate in at least one cyclic ether having b. pt. >110 degrees C, at standard press., in water opt. contg. flow control agents, protective colloid and/or wetting agents; (2) largely removing the cyclic ether and (3) grinding the polyesterimide precondensate suspension obtd. to particle sixes 5 (0.05-1.5) mu. Pref. used for prepn. of temp-resistant impregnating and luting compsns., laminates and pre-pregs, e.g. for impregnating glass and polyacrylamide webs and for bonding foils, papers and webs. Dispersions having higher concns. are more easily processed than the solns. Risk of fire is obviated.

Abstract: 1,247,522. Coatings. BADISCHE ANILIN & SODA-FABRIK A.G. 22 Nov., 1968 [24 Nov., 1967], No. 55442/68. Heading B2E. [Also in Division C3] Surface coating compositions having a high binder content and which are suitable for application to materials, such as wood, ceramics, plastics, glass and iron, aluminium, magnesium and alloys of these metals, are produced by polymerising in an organic liquid, in the presence of a free radical polymerisation initiator, a mixture (I) of: (A) 50 to 95% by weight of at least one copolymerizable ester of a monoolefinically unsaturated carboxylic acid having three to five carbon atoms and an alcohol having one to four carbon atoms, (B) 0.75 to 25% by weight of an N-methylolamide of a copolymerizable olefinically unsaturated carboxylic acid having three to five carbon atoms, which amide has been etherifled with an alcohol having one to eight carbon atoms, and (C) 0.5 to 40% by weight of at least one further copolymerizable monoolefinically unsaturated monomer other than a monomer of type (A) or (B), the sum of the percentages of (A), (B) and (C) being 100, and the components of the mixture (I) being selected so that a copolymer formed therefrom is substantially insoluble in the organic liquid; there being dissolved in the organic liquid, in an amount from 10 to 200% by weight with reference to the mixture (I), a copolymer (II) which contains polymerized units of: (A) 50 to 97% by weight of at least one copolymerizable ester of a monoolefinically unsaturated carboxylic acid having three to five carbon atoms and an alcohol having four to eighteen carbon atoms, (B) 2 to 49.5% by weight of an N-methylolamide of a copolymerizable olefinically unsaturated carboxylic acid having three to five carbon atoms, which amide has been etherified with an alcohol having one to eight carbon atoms, and (C) 0.5 to 48% by weight of at least one further copolymerizable monoolefinically unsaturated monomer other than a monomer of type (A) or (B), the sum of the percentages of (A), (B) and (C) being 100; the organic liquid containing at least 20% by weight of one or more aliphatic or hydroaromatic hydrocarbons; and the ratio of the sum of the weights of mixture (I) and copolymer (II) to the weight of the organic liquid being in the range from 1:4 to 4:1. Component (C) of (I) may be a vinyl carboxylate ester, a mono- (meth) acrylate ester of an alkanediol or oxaalkanediol, (meth) acrylamide, (meth) acrylonitrile, an N-vinyl heterocyclic compound, styrene, vinyl toluene or (meth) acrylic acid. In addition to the hydrocarbon component, the organic liquid may also comprise ketones, ethers, alcohols and esters. The compositions may additionally include aminoplast precondensates, e.g. of formaldehyde with urea, melamine or benzoguanamine, and also minor amounts of additives such as epoxy resins, phenol resins, alkyd resins, pigments, dyes, curing accelerators, e.g. p-toluene sulphonic acid, and flow-improving agents. The compositions can be applied to household articles, automobile parts and medical apparatus by methods such as dipping, pouring, spraying, brushing and rolling. Coatings obtained can be cured by baking at 100- 150C.

Abstract: A composition suitable for use in the treatment of textiles comprises an aqueous dispersion containing (a) a polyamide which is a co-condensate of 25-40% by weight of one or more lactams having 6-12 carbon atoms in the lactam ring or of equivalent omega-aminocarboxylic acids, 25-40% by weight of one or more salts of hexamethylene diamine with linear dicarboxylic acids having 6-12 carbon atoms, 25-40% by weight of one or more salts of 4,41-diamino-dicyclohexylmethane with linear dicarboxylic acids having 6-12 carbon atoms and 0-10% by weight of one or more other polyamide-forming substances and (b) a protective colloid which is a water-soluble copolymer having a K value of at least 90 and derived from 10-35% by weight of acrylic and/or methacrylic acid, 57.5-90% by weight of a mixture consisting of acrylamide and 5-40% by weight (on the whole of the monomers) of methacrylamide and 0-7.5% by weight of one or more other monomers. Suitable other polyamide-forming substances are dicarboxylic acids, omega-aminocarboxylic acids or diamines which are branched or contain a hetero atom in the chain, and C-substituted lactams. The other monomers in the protective colloid may be a -chloro-acrylic, phenylacrylic, crotonic, maleic, fumaric, itaconic, citraconic, mesaconic or vinylsulphonic acid or an anhydride, salt or ester thereof, methyl or ethyl acrylate or methacrylate, vinyl acetamide, N-dimethylacrylamide, N-methylacrylamide, N-ethylacrylamide or a vinyl lactam. Particularly preferred protective colloids contain 0.005-1% by weight of copolymerizable monomers containing N-methylol groups, e.g. derivatives of urea, melamine, dicyandiamide and guanidine containing N-methylol groups and groups with polymerizable olefinic double bonds and particularly N-methylolmethacrylamide and N-methylolacrylamide. The dispersion may contain 0.5-5% by weight of the protective colloid based on the weight of the polyamide. The dispersions may be prepared by mixing a solution of the polyamide in an organic solvent, e.g. ethanol, isopropanol, butanol or a mixture thereof, with water which contains the protective colloid and, if desired, distilling off all or part of the solvent. The dispersion may also contain polyolefines, polyacrylates, water repellents, dyes, pigments, thickening agents, organic solvents and reaction products, which may be etherified with alcohols containing up to four carbon atoms, of formaldehyde with urea, melamine, ethyleneurea, trimethyleneurea, 4,5-dihydroxy imidazolidone-(2), triazone (2) and its 5-alkyl and 5-hydroxy-alkyl derivatives having up to four carbon atoms in the alkyl or hydroxyl alkyl radical, 5-hydroxytrimethyleneurea or urones.
