摘要： Aqueous polyacrylate dispersions having improved flow characteristics are prepared by polymerizing esters of acrylic acid and/or methacrylic acid and alkanols of 1 to 10 carbon atoms, with or without admixture of styrene and/or vinyl esters and/or water-soluble monoolefinically unsaturated comonomers (the monomer feed being in the form of an emulsion), in aqueous emulsion in the presence of a free radical polymerization initiator, a protective colloid, a nonionic emulsifier and a regulator, at least a part of the protective colloid being introduced into an aqueous initial charge, and a water-soluble regulator being employed in the initial charge and in the feed.

摘要： Films obtained from paints based on conventional aqueous polymer dispersions exhibit improved wet adhesion to alkyd resin-coated substrates and improved blocking resistance if the paints contain polyglycidylamines which carry 2 or more glycidyl groups which are bonded to hydrogen-free nitrogens.

摘要： Binders which comprise (A) an aqueous emulsion of a copolymer A, having a glass transition temperature of 0-50.degree. C., of monoolefinically unsaturated carboxylic acid esters, with or without styrene, vinyl acetate, vinyl chloride and acrylonitrile, which copolymer contains, as copolymerized units, small amounts of monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids and/or their amides (of which the nitrogen atoms may or may not be alkyl-substituted and/or alkylol-substituted) and small amounts of monomers containing carbonyl groups, (B) from 0.05 to 1 mole, per mole of carbonyl groups present in the copolymer A, of a water-soluble aliphatic dihydrazine compound and (C) from 0 to 0.02 mole, per mole of dihydrazine compound, of a water-soluble zinc, manganese, cobalt and/or lead salt, or particularly suitable for use in paints and pebble dash renderings, since they give films which adhere particularly well to alkyd resin primers and which show particularly little tendency to whitening.
摘要翻译：包含（A）具有或不具有苯乙烯，乙酸乙烯酯，氯乙烯和丙烯腈的单烯属不饱和羧酸酯的玻璃化转变温度为0-50℃的共聚物A的水乳液的粘合剂，所述共聚物包含作为共聚单元，少量的单烯属不饱和一元羧酸和/或二羧酸和/或它们的酰胺（其中氮原子可以是或可以不是烷基取代和/或烷基取代的）和少量含有羰基的单体基团，每摩尔存在于共聚物A中的每摩尔羰基0.05〜1摩尔的水溶性脂族二肼化合物和（C）0〜0.02摩尔每摩尔二肼化合物的水溶性脂肪族二肼化合物，可溶性锌，锰，钴和/或铅盐，或特别适用于油漆和卵石破折影效果，因为它们提供了特别适合于醇酸树脂底漆的薄膜，其显示特别少美白的倾向。
