| 摘要 |
The present invention relates to a graft copolymer obtained by graft polymerization of 5-80 parts by weight of a rubber polymer, 20-95 parts by weight of a monomer including at least one selected from an aromatic vinyl monomer and a vinyl cyanide monomer. The rubber polymer has a micro structure and includes 21-30% of cis-1,4 bond, 47-60% of trans-1,4 bond, and 16-23% of 1,2 vinyl bond. The degree of swelling of the rubber polymer is 13-35. |
