    摘要: The use is described of particulate, water-insoluble and scarcely swellable polymers of ethylenically unsaturated monomers, which polymers contain, copolymerized, at least 20% by weight, based on the total weight of the monomers, of at least one &agr;,&bgr;-monoethylenically unsaturated monocarboxylic acid having from 3 to 6 carbons as filter aid for filtering aqueous liquids. Subject-matter of the invention are also water-insoluble, scarcely swellable polymers (popcorn polymers) that contain, copolymerized, &agr;,&bgr;-monoethylenically unsaturated carboxylic acids and styrene or styrene derivatives, and also a process for their preparation.
