Comb (block) copolymers (CBC) obtained by reaction of (I) (block) copolymers containing optionally substituted styrene (S) and maleic anhydride (MA) units and made by controlled radical polymerisation, with (II) polyalkylene oxide monoamines with prim. amino end groups, at 150[deg] C or above, followed by conversion of at least 25 mol% of the free acid groups into the salt form at below 100[deg] C (optionally after adding water). Independent claims are included for (1) paints, pastes or molding materials containing CBC as wetting and dispersion agent, plus filler(s), preferably a pigment, and optionally an organic or aqueous medium, binder(s) and/or other conventional additives, preferably conventional wetting and dispersion agents (2) pigments, the surface of which is modified with CBC . |
