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.

Abstract: Copolymers for detergents and cleaning agents The invention relates to copolymers as ingredients for detergents and cleaning agents, which contain monoethylenically unsaturated mono- and dicarboxylic acids, their hydroxyalkyl esters and, if appropriate, other ethylenically unsaturated compounds as monomer units, and are distinguished by a particular calcium-binding and magnesium-binding capacity, detergents and cleaning agents containing these copolymers, and their use in detergents and cleaning agents, in particular as sequestering agents and antiredeposition agents.

Abstract: A process wherein… (a) from 99 to 80 % by weight of maleic anhydride and… (b) from 1 to 20 % by weight of a monoethylenically unsaturated monomer which can be copolymerised with maleic anhydride, and, if desired,… (c) up to 10 % by weight of a crosslinking agent… are copolymerised in an aromatic hydrocarbon at a temperature of from 60 to 200 DEG C in the presence of a peroxy ester derived from a saturated or monoethylenically unsaturated carboxylic acid, and the anhydride groups of the copolymer are subsequently hydrolysed. … The copolymers prepared in this way are used as water-treatment agents.

Abstract: Paper, board and cardboard are produced by draining a pulp slurry in the presence of high molecular weight, water-soluble polymers of N-vinylamides as drainage aids, retention agents and flocculants. These polymers are particularly effective in a pulp slurry which has a high content of interfering substances and other phenolic compounds.
