    Abstract: The invention concerns copolymers of hydroxyalkyl vinyl ethers obtained by the cation-initiated or radical-initiated copolymerization of: (a) 99 to 1 % by wt. of hydroxyalkyl vinyl ethers; (b) 1 to 99 % by wt. of the addition products formed by the reaction of C2 to C4 alkylene oxides and hydroxyalkyl vinyl ethers and (c) 0 to 98 % by wt. of other copolymerizable monomers, as well as the use, as additives to washing and cleaning agents in proportions of from 0.1 to 50 % by wt., of such copolymers and of cation-polymerized or radical-polymerized hydroxyalkyl vinyl ethers containing, polymerized into the structure, the monomers given in (a) or (b), alone or mixed with other copolymerizable monomers.

    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.
