Preparation of concentrated polyacrylate dispersions |
摘要 |
Emulsion copolymerization of acrylic or methacrylic acid esters with from 0.3 to 10% by weight of alpha , beta -monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids and/or their amides, with or without up to 25% by weight of styrene, acrylonitrile, vinyl acetate and/or vinyl chloride, using the emulsion feed process, gives particularly concentrated copolymer dispersions if an emulsifier system of 0.01-5.0% by weight of a sulfuric acid half-ester of an oxyalkylated alkylphenol and 0.01-1% by weight of a dialkyl sulfosuccinate, where alkyl is of 6 to 18 carbon atoms, is employed and the polymerization is carried out at pH 2-6.
