Abstract: Copolymers contain, as characteristic polymerized monomer units, (a) 2 to 50 mol % vinylalkylether with 3 to 30 C atoms in the molecule; (b) 10 to 88 mol % monoethylenically unsaturated dicarboxylic acid anhydrides and (c) 10 to 88 mol % dialkylesters of monoethylenically unsaturated dicarboxylic acids. A process is disclosed for producing these copolymers by copolymerizing the monomers (a), (b) and (c) at temperatures between 40 and 180 C in the presence of radical-building initiators. Also disclosed is the use of the copolymers as film forming resins in hair sprays and in the form of alkaline metal, ammonium or alkaline earth metal salts as thickeners for aqueous systems, such as cosmetic and pharmaceutical compositions, textile printing pastes, liquid washing and cleaning agents.

Abstract: The preparation of copolymers of monoalkyl maleates or maleic acid and salts thereof and vinyl alkyl ethers by free-radical copolymerisation of maleic anhydride and vinyl alkyl ethers and subsequent reaction with alkanol or water and optionally metal hydroxides and/or oxides, where the vinyl alkyl ether component is in excess in the reaction mixture in each phase of the polymerisation, the free-radical copolymerisation is carried out in acetone, and the acetone is removed by distillation during or after the esterification or hydrolysis, the polymerisation initiators used being carboxylic acid peroxy esters derived from carboxylic acids having at least 8 carbon atoms. The copolymers obtained are used in cosmetic preparations.

Abstract: A process for producing copolymers from monoethylenically unsaturated monomers containing acid groups and from N-vinyl lactames and possibly from other monoethylenically unsaturated monomers by copolymerising the monomers in the presence of radical-forming polymerisation initiators in the manner of solution polymerisation in water at a pH of at least 6. An alkaline metal or earth metal base or a mixture thereof is used to adjust the pH of the aqueous reaction solution.
