    摘要： Agglomerated polymer particles of finely divided, water-soluble or water-swellable polymers containing ammonium carboxylate groups are prepared by azeotropic removal of water from water-in-oil emulsions of the water-soluble or water-swellable polymers which contain ammonium carboxylate groups in the presence of from 0.1 to 40% by weight, based on the polymers, of polyalkylene glycols which have an agglomerating effect and which are obtainable by an addition reaction of C2-C4-alkylene oxides with alcohols, phenols, amines or carboxylic acids and contain at least two polymerized alkylene oxide units and additionally of from 0.1 to 20% by weight, based on the polymers, of protective colloids which are obtainable by free radical copolymerization of C8-C40-monoolefins with monoethylenically unsaturated C4-C6-dicarboxylic anhydrides by a mass polymerization method at from 80 to 300° C. to give copolymers having molecular weights of from 500 to 20,000 g/mol, and said agglomerated polymer particles are used as thickeners for textile pigment print pastes.
