摘要：The invention relates to powder-form, cross-linked polymer compositionscontaining the following: a) 55-99.9 wt. % of at least one polymerised, ethylenicallyunsaturated, polymerisable monomer containing acid groups, said monomer(s) beingneutralised to at least 25 mol. %; b) 0-40 wt. % polymerised, unsaturated monomers thatare copolymerisable with a); c) 0.01-5.0, preferably 0.1-2.0 wt. % of one or more cross-linking agents; and d) 0-30 wt. % of a water-soluble polymer, the proportions by weighta) to d) being in relation to the water-free polymerizate composition and the sum of thecomponents always being 100 wt. %. The inventive compositions can be obtained bycontinuous polymerisation during which at least one parameter that influences thepolymerisation is varied according to a recurrent pattern. The invention also relates to amethod for producing the inventive polymer compositions and to their use.
