When the copolymer thus obtained is incorporated into, for example, an acrylonitrile-butadiene-styrene terpolymer composition, thermoplastic resin compositions not coloring upon molding are obtained with a good impact resistance and heat resistance.Type: GrantFiled: July 17, 1981Date of Patent: January 24, 1984Assignee: Denki Kagaku Kogyo Kabushiki KaishaInventors: Norio Yagi, Hisashi Chiba, Yutaka Mitsuda, Yasuaki Sakano, Masaki Aikawa
