摘要
Aqueous low-emulsifier dispersions of emulsion copolymers which contain, as copolymerized units, (a) from 35 to 55% by weight of butadiene, (b) from 35 to 60% by weight of styrene, (c) from 1 to 3% by weight of alpha , beta -monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids of 3 to 6 carbon atoms, (d) from 1 to 3% by weight of amides of alpha , beta -monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids of 3 to 5 carbon atoms, (e) from 1 to 4% by weight of N-methylolamides of alpha , beta -monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids of 3 to 5 carbon atoms, or their alkyl ethers, and (f) from 1 to 3% by weight of acrylic acid and/or methacrylic acid monoesters of alkanediols of 2 to 6 carbon atoms, the emulsion containing, as emulsifier, from 0.1 to 0.8% by weight, based on emulsion copolymers, of fatty alcohol-sulfonates and/or alkylbenzenesulfonates, where alkyl is of 12 to 16 carbon atoms, are of particular value as binders for aqueous anti-corrosion paints.
