Patent ID: 6875812

Claim:
A resin composition containing a graft copolymer obtained by reacting 1 to 99 parts by weight of (a) an amino group-containing hydrogenated block copolymer obtained through hydrogenation of an amino group-containing block copolymer with 99 to 1 part by weight of (b) a functional group-containing polyphenylene ether having any one functional group selected from the group consisting of a carboxyl group, an acid anhydride group and an epoxy group and/or (c) a functional group-containing polyolefin having any one functional group selected from a group consisting of a carboxyl group, an acid anhydride group and an epoxy group, wherein the amino group-containing block copolymer is obtained by reacting a living terminal lithium ion group of a vinyl aromatic compound-conjugated diene compound block copolymer chain, which is formed using an organic lithium compound as a polymerization initiator in a hydrocarbon solvent with a cyclic compound represented by the following formula (1) or (2), wherein R 1 and R 2 are independently of each other an alkyl or alkoxy group having 1 to 4 carbon atoms, Y is an oxygen atom or a sulfur atom, and n is an integer of 2 to 4, wherein R 3 is an alkyl, cycloalkyl or alkoxy group having 1 to 6 carbon atoms, Z is an oxygen atom or a sulfur atom, and m is an integer of 3 or 4, provided that one or more hydrogen atoms in the polymethylene chain may be substituted with an alkyl group having 1 to 6 carbon atoms.
