Abstract:
An aromatic vinyl graft copolymer which is a graft copolymerization product of an aromatic vinyl monomer (H) and ethylene copolymer macromer (I) which has in the molecular chain a vinyl group attributed to a diene monomer having a styrenic vinyl group;wherein the ethylene copolymer (I) is obtained by copolymerization of an aromatic vinyl monomer (A), ethylene (B) and a diene monomer having a styrenic vinyl group (C); wherein a recurrent unit attributed to aromatic vinyl monomer (A) is 1-98 mol %, a recurrent unit attributed to ethylene (B) is 1-98 mol %, and a recurrent unit attributed to the diene monomer having the styrenic vinyl group (C) is 0.001-10 mol %.
