Method for the production of polymers by free radical polymerization of a) 99.99 to 10% by weight of at least one α, β ethylenically unsaturated compound with at least one cation and / or cationic generating group per molecule, b ) 0 to less than 25% by weight of at least one monoethylenically unsaturated compound containing amido groups other than a), c) 0.01 to 5% by weight of an interlacer, d) 0 to 15% by weight of at least one monoethylenically unsaturated compound d1) containing at least one group selected from the group consisting of C5-C30 alkyl, where appropriate substituted, C5-C30 alkenyl, C5-C8 cycloalkyl, aryl, arylalkyl and heteroaryl and / or a precursor d2) reagent of component d), e) 0 to 30% by weight of another monoethylenically unsaturated compound other than a) to d), provided 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 the components s a) to e) of a compound containing polyether, characterized in that, - in the course of the method at least two different water insoluble initiators A and B are used and - the polymerization is precipitation polymerization. |
