Patent ID: 7118694

Claim:
A composition IIa consisting of a) 1 to 95% by weight of a solid III which is a silicate, having a primary particle size of 5 mn to 20 microns, and b) 5 to 99% by weight of a polymeric mass IV obtained by polymerizing b1) 5 to 100% by weight based on the mass IV of a condensation product V of α) at least one compound VI which is capable to react with a carboxylic acid or a sulfonic acid or a derivative thereof or a mixture of two or more thereof, and β) at least one mole per mole of the compound VI of a carboxylic acid or a sulfonic acid VII which exhibits at least one radically polymerizable functional group, or a derivative thereof or a mixture of two or more thereof, wherein the carboxylic acid or sulfonic acid VII or a derivative thereof is selected from the group consisting of α,β-unsaturated carboxylic acids or derivatives thereof, vinyl esters of aliphatic or aromatic carboxylic acids, allyl esters of aliphatic or aromatic carboxylic acids and mixtures of two or more thereof, and b2) 0 to 95% by weight, based on the mass IV, of a further compound VIII having a number average molecular weight of at least 5000 and having polyether segments in the main or side chain.
