Abstract:
A cationic polymer obtained by free-radical copolymerization of components consisting of(a) from 50 to 70% by weight of one or more monomers of the formula I X=O, NR1 R1=H, C1=C8-alkyl R2=tert-butyl, (b) from 5 to 45% by weight of one or more monomers of formula II where n=1 to 3,(c) from 5 to 40% by weight of a monoethylenically unsaturated monomer having at least one amine-containing group where up to 40% by weight, based on (a), (b), and (c) of the monomer (a) can be replaced by a monomer of the formula I where R2=C2-C22-alkyl.
