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: 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 calicum-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 anti-redeposition agents.

Abstract: The process is carried out as a precipitation polymerisation by copolymerising the monomers on which the copolymers are based, if desired in the presence of up to 2% by weight, based on the monomers, of a crosslinking agent containing at least two ethylenically unsaturated double bonds, and in the presence of polymerisation initiators in, as solvent for the monomers, an ester which contains at least 5 carbon atoms and is derived from saturated aliphatic carboxylic acids and monohydric saturated alcohols.

Abstract: A process for the preparation of pulverulent copolymers which are soluble in water or dissolve therein in the form of salts by copolymerisation of water-soluble monomers, optionally together with water-insoluble monomers, in liquid carbon dioxide or in supercritical carbon dioxide under pressure in the presence of free-radical-forming initiators.
