Procedure
Molding was carried out using a resin composition composed of 80% by weight of α-methylstyrene-acrylonitrile copolymer having a composition consisting of 78% by weight of α-methylstyrene and 22% by weight of acrylonitrile, which contained 42% by weight of a copolymer component having a composition containing 82% by weight of α-methylstyrene, and 20% by weight of a graft copolymer obtained by graft polymerization of 60% by weight of polybutadiene rubber with 28% by weight of styrene and 12% by weight of acrylonitrile. The HDT of the resulting sample was 118° C. (Sample No. 7)
