<P>PROBLEM TO BE SOLVED: To provide a graft copolymer excellent in impact resistance and flowability by using a rubbery polymer having excellent polymerization stability, a thermoplastic resin composition obtained from the graft copolymer and a molded product made from the resin composition. <P>SOLUTION: The graft copolymer is obtained by graft-copolymerizing 20-95 pts.wt. of at least one kind of a monomer selected from an aromatic vinyl monomer, vinyl cyanide monomer and other vinyl-based monomer copolymerizable with the two kinds of monomer with 5-80 pts.wt. of a rubbery polymer. The microstructure of the rubbery polymer includes 21-30% cis-1,4 bond, 47-60% trans-1,4 bond and 16-23% 1,2-vinyl bond and the swelling ratio of the rubbery polymer is 13-35. <P>COPYRIGHT: (C)2013,JPO&INPIT |
