Abstract

Detergents which contain from 0.01 to 20% by weight of oxyalkylated, carbonyl-containing polymers can be prepared by reacting. (A) a polymer which contains, as copolymerized units, one or more monoethylenically unsaturated C.sub.3 -C.sub.6 -carboxylic acids with (B) ethylene oxide, propylene oxide, n-butylene oxide, isobutylene oxide or a mixture of these, in an aqueous medium at up to 150.degree.
