摘要：
Detergents contain added graft copolymers which have an antiredeposition action and are obtainable by grafting polyalkylene oxides having a number average molecular weight of from 2000 to 100,000 with vinyl acetate in a weight ratio of from 1:0.2 to 1:10, and up to 15% of whose acetate groups may be hydrolyzed.
