Abstract

PURPOSE: To obtain a copolymer which discolors little when heated during molding, by copolymerizing an α-substituted aromatic vinyl compound with an unsaturated nitrile compound by using a specified organic peroxide as a catalyst.
CONSTITUTION: Titled copolymer is obtained by bulk-polymerizing or solution- polymerizing 100pts.wt. mixture of an α-substituted aromatic vinyl compound, e.g., α-methylstyrene, and an unsaturated nitrile compound, e.g., acrylonitrile, at 80W130°C in the presence of 0.01W0.5pt.wt. organic peroxide of formula I or II, wherein R1W2 are each a 1W11C alkyl, e.g., t-butyl peroxyisopropylcarbonate, diisopropyl peroxydicarbonate. The copolymer produced is used alone or in admixture with a resin such as AS, ABS or AES.
