Patent ID: 8247507

Claim:
A method for producing polymers by radically polymerizing a) 99.99 to 10% by weight of at least one α,β-ethylenically unsaturated compound with at least one cationogenic and/or cationic group per molecule, b) 0 to less than 25% by weight of at least one monoethylenically unsaturated amide-group-containing compound different from a), c) 0.01 to 5% by weight of a crosslinker, d) 0 to 15% by weight of at least one monoethylenically unsaturated compound d1) comprising at least one group selected from the group consisting of optionally substituted C 5 -C 30 alkyl, C 5 -C 30 alkenyl, C 5 -C 8 cycloalkyl, aryl, arylalkyl and hetaryl, e) 0 to 30% by weight of further monoethylenically unsaturated compounds different from a) to d), with the proviso that the amounts of components a) to e) add up to 100% by weight, in the presence of f) 0 to 70% by weight, based on the sum of components a) to e), of a polyether-containing compound, wherein in the course of the process at least two different water-insoluble initiators A and B are used.
