  • Patent number: 5155171
    Abstract: Copolymers of monoalkyl maleates or maleic acid and salts thereof and vinyl alkyl ethers are prepared by free radical copolymerization of maleic anhydride and vinyl alkyl ethers and subsequent reaction with an alkanol or water and optionally metal hydroxides and/or oxides in a process wherein at every stage of the polymerization the vinyl alkyl ether component is present in excess in the reaction mixture, the free radical copolymerization is carried out in acetone and the acetone is removed by distillation during or after the esterification or hydrolysis, which comprises using a peroxyester of a carboxylic acid of 8 or more carbon atoms as polymerization initiator. The copolymers obtained are used in cosmetic preparations.
