    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.

    摘要： The present invention relates to a process for preparing polymer powders from aqueous polymer dispersions in which the dispersed polymer P comprises in copolymerized form: i) at least one vinylaromatic monomer (a), ii) 1,3-butadiene as monomer (b), and iii) one or more monomers (c) different than the monomers (a) and (b), which comprises drying the aqueous polymer dispersion in the presence of polyvinyl alcohol as drying agent. The present invention also relates to the polymer powders obtainable by this process and to the use of these polymer powders as binders in paints, varnishes and coating compositions generally, in adhesives, and for modifying mineral construction materials. The present invention also relates to mineral construction materials in the form of dry formulations comprising the polymer powders of the invention.
