Abstract

Abstract A thermoplastic resin composition comprises the following components (A) and (B): component (A): 10 to 90% by weight polyphenylene ether resin, component (B): 90 to 10% by weight unsaturated copolymer resin obtained by copolymerizing at least one α-olefin having 2 to 12 carbon atoms and a diene compound having 4 to 15 carbon atoms, and containing 0.01 to 50 mol % of diene compound. This resin composition has excellent resistance to organic solvents and superior mechanical properties.
