Abstract: PROBLEM TO BE SOLVED: To obtain a graft copolymer useful as a compatibilizer by reacting a specific polyarylene ether, a thermoplastic polyamide, and a specific copolymer in a specified wt. ratio. SOLUTION: This graft copolymer is obtd. by reacting 5-85wt.% polyarylene ether of which at least 30% of the terminals groups are reactive with functional groups of the below-described copolymer, 5-85wt.% thermoplastic polyamide, and 10-99wt.% copolymer formed from an arom. vinyl compd. (e.g. styrene), a cyclic α, β-unsatd. discarboxylic anhydride (e.g. maleic anhydride), a cyclic α,β-unsatd. dicarboximide (e.g. N-phenylmaleimide), and other copolymerizable monomers, the sum of the reactants being 100wt.%. When this graft copolymer is used as a compatibilizer for a polymer blend based on a polyarylene ether and a polyamide, a molded item excellent in resistance to heat distortion can be obtd.
