GRAFT COPOLYMER, THERMOPLASTIC RESIN COMPOSITION, AND MOULDED ARTICLE OF SAID RESIN COMPOSITION

摘要

This graft copolymer is obtained by polymerizing a vinyl monomer mixture (m1) including an aromatic vinyl compound and a vinyl cyanide compound, in the presence of: an ethylene/α-olefin copolymer (A) which has a mass average molecular weight (Mw) in the range of 17×104 to 35×104, and a molecular weight distribution (Mw/Mn) in the range of 1-3; or a crosslinked ethylene/α-olefin copolymer (C) obtained by crosslinking the ethylene/α-olefin copolymer (A).
