CA 2423518

Use of water-soluble of water-dispersible, film-forming graft polymers obtainable by free-radical polymerization of (a) vinyl esters of aliphatic C1-C24 carboxylic acids in the pres- ence of (b) polyethers with an average molecular weight (number average) of at least 300, as coating compositions for particulate laundry detergents and cleaning products and as packaging material for laundry detergents, cleaning products, and laundry aftertreatment compositions for producing individual portions for dosing the products in the washing process together with the packaging material.

L'invention concerne l'utilisation de polymères greffés filmogènes, hydrosolubles ou se dispersant dans l'eau, produits par polymérisation radicalaire (a) d'esters vinyliques d'acides carboniques C1-C24 aliphatiques, en présence de (b) polyéthers de poids moléculaire moyen (moyenne en nombre) d'au moins 300. Ces polymères servent de moyens d'enduction pour des agents de nettoyage et de lavage sous forme de particules, et de matériaux de conditionnement pour des agents de nettoyage, de lavage et de retraitement du linge, le dosage des agents dans le processus de lavage étant réalisé sous forme de doses individuelles, en combinaison avec le matériau de conditionnement.
