    Abstract: The use of partially esterified copolymers which can be obtained by copolymerisation of (a) at least one C4- to C28-olefin and (b) ethylenically unsaturated dicarboxylic anhydrides with 4 to 8 C atoms in the molar ratio 1:1 and subsequent partial esterification of the copolymers with reaction products of (A) C1- to C30-alcohols, C8- to C22-fatty acids, C1- to C12-alkylphenols or secondary C2- to C30-amines with (B) at least one C2- to C4-alkylene oxide or tetrahydrofuran in the molar ratio (A):(B) of 1:2 to 50 and hydrolysis of the anhydride groups of the copolymers to carboxyl groups, where the partial esterification of the copolymers is continued until more than 5 to 50% of the carboxyl groups in the copolymers are esterified, as additive to liquid detergent compositions in an amount of 0.1 to 20% by weight and liquid detergent compositions which contain the partially esterified copolymers.

    Abstract: O.Z. 0050/40290 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 moxe C4-C28-olefins and (b) ethylenically unsaturated dicarboxylic anhydrides of from 4 to 8 carbon atoms in a molar ratio of 1:1 and subsequent partial esterification of the copolymers of the reaction products (A) C1-C30-alcohols,C8-C22-fatty acids,C1-C12-alkylphenols or secondary C2-C30-amines with (B) one or more C2-C4-alkylene oxides or tetrahydrofuran in a molar ratio of (A):(B) of from 1:2 to 1:50 and hydrolysis of the anhyaride 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.
