    摘要： A resin composition is a blend of, by wt:
    a) 20-80% of at least partly crystalline homo- or co­polymer of an olefin, or an oxidation, halogenation or sulfonation product thereof (preferably of ethylene, propylene, butene-1, 3-­methylbutene-1 or 4-methylpentene-1) which may include a rubbery α-olefin polymer; b) 20-80% of a polyphenylene ether resin which can have up to 4 substituents (preferably dialkyl) on the phenylene ring, or a copolymer thereof; c) 4-50% of a hydrogenated copolymer, of mol wt 5,000 to 500,000 g/mol, of a block of an alkenyl aromatic compound which can have various substituents on the benzene ring and alkenyl group (e.g. styrene) and 45-80 wt% of a block of a conjugated diene, the copolymer being hydrogenated so that up to 50% of the unsaturated bonds in the aliphatic chain are non-hydrogenated; and
    optionally (a) up to 50 part, per 100 of (a)+(b)=(c), of a diamide compound. The composition is easily molded to make components such as automobile parts having good mechanical properties.
