摘要:
Graft polymers containing (A) a polymeric grafting base devoid of monoethylenically unsaturated units, and (B) polymeric side chains formed by polymerization of a cyclic N-vinylamide of the general formula I where R is C1–C5-alkyl and R1 is hydrogen or C1–C4-alkyl, wherein said side chains (B) account for ≧60% by weight of the total polymer.
