Abstract
A method of preparing a copolymer of an alpha-alkyl styrene and/or an alpha-acyloxy styrene and an alkyl methacrylate, characterized by heating an alpha-alkyl styrene monomer and/or an alpha acyloxy styrene monomer in which the alkyl group/or the acyl group does not contain more than 6 carbon atoms and an alkyl monomer methacrylate in which the alkyl group contains no more than 4 carbon atoms at a temperature of 70 to 160º C in the presence of 0.01 to 0.8 % by weight based on the monomers of a free radical polymerization catalyst to form a copolymer containing from 1 to 55% by weight of alpha-alkylstyrene and/or alpha-acyloxystyrene and 45 to 99% by weight of methacrylate of alkyl and having an intrinsic viscosity as measured in dioxane at 25º C of at least 0.20.
