摘要

The invention concerns mixture Ia, containing a mixture IIa, consisting of: a) between 1 and 95 wt % of a solid III, preferably a basic solid III, with a primary particle size of between 5 nm and 20 mu m; and b) between 5 and 99 wt % of a polymer composition IV, obtained by the polymerization of: b1) between 5 and 100 wt %, relative to the composition IV, of a condensation product V comprising: alpha ) at least one compound VI which can react with a carboxylic acid or a sulphonic acid or a derivative or a mixture of two or more thereof; and beta ) at least one mol per mol of the compound VI of a carboxylic acid or sulphonic acid VII which comprises at least one radically polymerizable functional group, or a derivative thereof or a mixture of two or more thereof; and b2) between 0 and 95 wt %, relative to the composition IV, of a further compound VIII with an average molecular weight (number average) of at least 5000 with polyether segments in the main or side chain. The portion by weight of mixture IIa in mixture Ia is between 1 and 100 wt %.
