    Abstract: 1,240,320. Coating composition. BADISCHE ANILIN- & SODA-FABRIK A.G. 11 Dec., 1968 [13 Dec., 1967], No. 58905/68. Heading C3P. A coating composition contains a copolymer (I) of (A) 50 to 95% by weight of an ester of a monoolefinically unsaturated carboxylic acid having three to five carbon atoms and an alcohol having one to eight carbon atoms; (B) 0À75 to 25% by weight of at least one N- methylol amide of an olefinically unsaturated carboxylic acid have three to five carbon atoms which has been etherified with an alcohol having one to eight carbon atoms; and (C) 0 to 40% by weight of at least one other copolymerizable olefinically unsaturated monomer, dispersed in an organic liquid, said dispersion having been prepared by polymerizing the monomers in the organic liquid, in the presence of both a freeradical initiator and a polymer (11) and/or polycondensate (11) having a molecular weight of more than 1200 which is compatible with the copolymer (1), which is soluble in the organic liquid and has a dispersing action. In the examples (1) ethyl acrylate, acrylic acid, N-nbutoxymethyl methacrylamide and 1,4-butanediol monoacrylate are copolymerized in an organic solvent in the presence of benzoyl peroxide and in the presence of a dispersing agent which'is a copolymer of styrene, 2-ethylhexyl acrylate and N-vinyl imidazole, (2) the monomers of (1) and additionally methyl methacrylate are copolymerized in an organic solvent in the presence of benzoyl peroxide and in the presence of a dispersing agent which is a copolymer of styrene, 2-ethyl hexylacrylate, N- vinyl imidazole, N-vinyl caprolactam and methyl methacrylate, (3) t-butyl acrylate, 2- ethyl hexyl acrylate, di-n-butyl maleate, methyl methacrylate, vinyl propionate, N,N-diethylacrylamide, acrylonitrile, acrylic acid, N-nbutoxymethylacrylamide, N - methoxymethyl methacrylamide and 2-ethyl acrylate are copolymerized in an organic solvent in the presence of benzoyl peroxide, di-tert-butyl per-' oxide and azoisobutyronitrile in the presence of a dispersing agent which is a copolymer of styrene, 2-ethylhexyl acrylate, n-butyl acrylate and N-vinyl pyrrolidone, (4) methylmethacrylate, ethyl acrylate, acrylic acid and N-butoxymethylmethacrylamide are copolymerized in an organic solvent in the presence of benzoyl peroxide and a dispersing agent which is a condensate of phthalic acid and glycerol modified with linseed oil, and (5) ethyl acrylate, butanediol acrylate acetylacetate, N-butoxymethylmethacrylamide, butanediol monoacrylate, styrene and acrylic acid are copolymerized as in (4) above.

    Abstract: In order to prepare polyester or polyetherpolyester polyols, polyols, preferably di- to hexafunctional polyether polyols having hydroxyl numbers from 15 to 250 are esterified with at least one carboxylic acid anhydride, preferably phthalic acid anhydride, in the presence of N-methylimidazole, triethylenediamine, and/or triphenylphosphine as catalysts to form a carboxylic acid half-ester, and said half-ester is then oxyalkylated with at least one alkylene oxide, preferably ethylene oxide, in the presence of N-methylimidazole, triethylenediamine, triphenylphosphine, thiodialkylene glycol, employing a mixture of at least two of the compounds cited as catalysts.
