CA 2420938

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, in 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 monomers 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 the 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.

Utilisation de polymères greffés qui sont obtenus par polymérisation de (A) 10 à 95 % en poids de monomères greffés contenant, par rapport à (A), (a) 1 à 99 % en poids d'au moins un ester de vinyle, (b) 1 à 99 % en poids d'au moins un N-vinyllactame, (c) 0 à 90 % en poids d'au moins un autre monomère monoéthyléniquement insaturé pouvant être copolymérisé avec les monomères (a) et (b) et (d) 0 à 5 % en poids d'au moins un monomère contenant au moins deux liaisons doubles éthyléniquement insaturées non conjuguées dans la molécule, en présence de (A) 5 à 90 % en poids d'au moins un polymère (B) choisi parmi des oxydes de polyalkylène qui possèdent au moins 3 unités d'un oxyde d'alkylène C¿2?-C¿4? et des polytétrahydrofurannes qui possèdent au moins 3 unités de tétraméthyloxyde, ainsi que leurs mélanges, en tant que substances empêchant les matières textiles de grisailler lors du lavage et du traitement postérieur desdites matières.
