Abstract: 1,139,202. Aqueous dispersions of vinyl ester polymers. BADISCHE ANILIN- & SODAFABRIK A.G. 12 May, 1966 [13 May, 1965], No. 21032/66. Heading C3P. Aqueous dispersions of vinyl ester polymers are prepared by polymerizing a vinyl ester of a linear or branched monocarboxylic acid having 2 to 18 carbon atoms, alone or with up to 35% by weight on the amount of monomers of at least one ester of acrylic acid and/or methacrylic acid with an alcohol containing one to eight carbon atoms and/or with up to 10% by weight on the amount of monomers of at least one other copolymerizable ethylenically unsaturated compound in an aqueous medium in the presence of a catalyst and 0À5 to 6% by weight on the amount of monomers of an acrylamide copolymer prepared in aqueous solution from 15 to 82% by weight of acrylamide, 15 to 82% by weight of methacrylamide, 3 to 30% by weight of acrylic acid and/or methacrylic acid and 0 to 12% by weight of at least one other ethylenically unsaturated compound, and having a K value of at least 50, and adding 0À2 to 5% by weight on the amount of monomers of a nonionic and/or anion-active polyalkylene oxide derivative. In examples are used: a sulphonated adduct of ethylene oxide and isooctylphenol, an adduct of ethylene oxide and castor oil, dimethyl phthalate, vinyl propionate, potassium persulphate, ammonia, tertiary-butyl acrylate, acrylic acid, sodium salt of a paraffin sulphonic acid, dibutyl phthalate, ethenoxylated coconut oil fatty acid alcohol, ethenoxylated polypropylene oxide and acrylamide.
