The present invention provides resin materials endowed with excellent heat resistance, solvent resistance, tensile elongation, toughness, and transparency. Specifically, there are provided an ethylene copolymer having a vinyl group attributed to a diene monomer in the molecular chain and comprising an aromatic vinyl monomer (A), ethylene (B) and a diene monomer (C), and an aromatic vinyl graft copolymer which is a graft copolymerization product of an aromatic vinyl monomer (H) and an ethylene copolymer macromer (I). |
