Abstract:
A granular material obtainable by pressing mixtures of at least one carboxyl-containing polymer as main component and at least one oil-soluble component, wherein use is made of a polymer component obtainable by free-radical-initiated copolymerization of monomer mixtures comprisinga) from 50 to 99.93% by weight of a monoethylenically unsaturated C3-C6-monocarboxylic acid, a monoethylenically unsaturated C4-C8-dicarboxylic acid or their anhydrides or salts or mixtures of the specified carboxylic acids, their anhydrides and/or salts, b) from 0.05 to 5% by weight of one or more compounds having at least two ethylenically unsaturated, nonconjugated double bonds in the molecule as crosslinker, c) from 0.02 to 10% by weight of at least one C1-C30-alkyl (meth)acrylate and d) from 0 to 50% by weight of other water-insoluble monomers copolymerizable with the monomers (a), (b) and (c).
