摘要：
A process for the preparation of copolymers of styrene and/or its derivatives by polymerization of one or more aromatic monovinyl compounds and acrylonitrile and/or methacrylonitrile wherein up to 75% by weight of the monomer mixture may be replaced by C.sub.1 --C.sub.20 -alkyl esters of acrylic and/or methacrylic acid and polymerization is carried out in the presence of from 0.01 to 10% by weight, based on the total quantity of monomers, of one or more enol ethers derived from aliphatic or cycloaliphatic aldehydes or ketones.
