Abstract: 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 C 1 -C 5 -alkyl and R 1 is hydrogen or C 1 -C 4 -alkyl, wherein said side chains (B) account for >=60% by weight of the total polymer.

Abstract: The invention relates to the use of grafted polymers as greying inhibitors during the washing and aftertreatment of textile goods. Said polymers are obtained by polymerising A) 10 to 95 wt. % of grafted monomers containing, i n relation to A), a) 1 to 99 wt. % of at least one vinyl ester, b) 1 to 99 wt. % of at least one N-vinyl lactam, c) 0 to 90 wt. % of at least one other monoethylenically unsaturated monomer which can be copolymerised with monome rs a) and b), and d) 0 to 5 wt. % of at least one monomer having at least two ethylenically unsaturated, non-conjugated double bonds in the molecule, in t he presence of A) 5 to 90 wt. % of at least one polymer B), chosen from polyalkylene oxides containing at least 3 units of a C2 to C4 alkylene oxide , and polytetrahydrofuranes containing at least 3 units of tetramethyl oxide units, and the mixtures thereof.
