    摘要： Polymer dispersions comprise at least one copolymer which contains, as polymerized monomers, a) from 25 to 70% by weight of at least one conjugated aliphatic diene, b) from 25 to 70% by weight of at least one vinylaromatic monomer, c) from 2.5 to 15% by weight of at least one monoester of a C2-C10-alkanediol with acrylic acid or methacrylic acid or c′) from 0.1 to 10% by weight of at least one alkylpolyethylene glycol (meth)acrylate of the formula (I) where R1 is hydrogen or methyl, R2 is C1-C4-alkyl and n is an integer from 1 to 100, or c″) from 2 to 15% by weight of a mixture of the monoester c) and the alkylpolyethylene glycol (meth)acrylate c′), d) from 0 to 1.0% by weight of ethylenically unsaturated monomers which have at least one acid group, or salts thereof, e) from 0 to 5.0% by weight of ethylenically unsaturated nitriles and f) from 0 to 1.0% by weight of amides of &agr;,&bgr;-ethylenically unsaturated mono- and dicarboxylic acids. The polymer dispersions described are suitable, inter alia, as additives in building materials based on hydraulic binders.
