ABSTRACT:
There are disclosed a graft copolymer formed by grafting a styrenic monomer onto a high polymer having double bonds in the side chain to constitute highly syndiotactic polystyrenic chain as the graft component, the graft copolymer having a content of graft component of 0.005 to 99% by weight and a reduced viscosity of 0.01 to 30 dl/g as measured at a concentration of 0.05 g/dl in 1,2,4-trichlorobenzene at 135.degree. C. or a melt index of 0.001 to 500 g/10 minutes as measured at 300.degree. C. under a load of 2.16 kg; a process for efficiently producing the above graft copolymer using a catalyst comprising specific components; and a resin composition comprising the above graft copolymer, a highly syndiotactic styrenic polymer or other thermoplastic resin and, when necessary, an inorganic or organic filler. The above graft copolymer and resin composition are excellent in resistance to heat and chemicals, electrical properties, moldability, compatibility, impact resistance, etc.
