PURPOSE:To provide a resin composition having excellent mechanical strength, solvent resistance and moldability and composed of a polyolefin, a polyphenylene ether, a specific block copolymer and an ethylenic elastomer modified with an unsaturated monocarboxylic acid (derivative). CONSTITUTION:The objective composition is produced by compounding (A) 20-95wt.% of a polyolefin resin (preferably crystalline propylene polymer), (B) 80-5wt.% of a polyphenylene ether resin (preferably polymer of 2,6- dimethylphenol). (C) 3-45 pts.wt. (based on 100 pts.wt. of A+B) of a block copolymer of a partially hydrogenated alkenyl aromatic compound and isoprene and containing 20-80wt.% of the alkenyl aromatic compound unit (preferably styrene) and (D) 3-45 pts.wt. (based on 100 pts.wt. of A+B) of a polymer produced by grafting 0.05-10 pts.wt. of an unsaturated monocarboxylic acid (derivative) to 100 pts.wt. of an ethylene-alpha-olefin copolymer having an ethylene content of 30-93mol%. |
