摘要: A novel graft copolymer composition comprising 30 to 90 wt. % of a graft copolymer containing substantially no polyphenylene ether homopolymer and 10 to 70 wt. % of a styrene type compound polymer having a number average molecular weight in the range from 50,000 to 200,000. The graft copolymer is prepared by graft polymerizing 20 to 200 parts by weight of a styrene type compound on an oligophenylene ether with a polymerization degree of 60 to 90. The composition has excellent resistance to creep.

摘要: A graft copolymer free from polyphenylene ether homopolymers is prepared by polymerizing 20 to 200 parts by weight of a styrene type compound at a temperature in the range from 130* to 200*C in the presence of 100 parts by weight of a polyphenylene ether and 0.1 to 15 parts by weight of a radical initiator. The graft copolymer is excellent in moldability and is also useful in making films, sheets, fibers, etc.
