    摘要： Liquid, alkaline detergent formulations which contain as essential constituents a surfactant, water and 0.1-20% by weight of partially esterified copolymers are obtainable by the copolymerization of(a) one or more C.sub.4 -C.sub.28 -olefins and(b) ethylenically unsaturated dicarboxylic anhydrides of from 4 to 8 carbon atomsin a molar ratio of 1:1 and subsequent partial esterification of the copolymers of the reaction products(A) C.sub.1 -C.sub.30 -alcohols, C.sub.8 -C.sub.22 fatty acids, C.sub.1 -C.sub.12 -alkylphenols or secondary C.sub.2 -C.sub.30 -amines with(B) one or more C.sub.2 -C.sub.4 -alkylene oxides or tetrahydrofuranin a molar ratio of (A):(B) of from 1:2 to 1:50 and hydrolysis of the anhydride groups of the copolymer to carboxyl groups, the partial esterification of the copolymers being carried on until more than 5 to 50% of the carboxyl groups of the copolymers have been esterified.
