Abstract
PURPOSE: To obtain a copolymer having improved hue and heat resistance, by copolymerizing acrylonitrile with a styrene monomer in the presence of specific two or more types of catalysts.
CONSTITUTION: Acrylonitrile is copolymerized with methylstyrene in the presence of 0.005W0.5wt.% each based on the monomer mixture of (A) a catalyst comprising an azo compound, e.g. 2,2'-azobisisobutyronitrile, or an organic peroxide free from aromatic rings, and (B) a catalyst comprising an organic peroxide of formula I or II: (R1 and R2 are the same or different alkyl groups; R3 is alkylene group; R4 is alkoxycarbonyl group) solely or its mixture to give a copolymer having improved hue and thermal stability with a low residual volatile content.
