Abstract
Abstract A moldable composition comprises; by weight of components (1) + (2); (1) 50-97% of a polyphenylene ether (which may be a copolymer), e.g. poly(2,6-dimethylphenol), of a mol. wt. so as to have intrinsic viscosity of 0.35-0.7 dl/g at 30 DEG C, and a polyamide resin (e.g. a nylon); (2) 3-50% of a block copolymer A-B @@A-B@@@@A)n where m=0 or an integer, n=0 or 1, A is an aromatic vinyl compound (e.g. styrene) and B is a conjugated diene (e.g. butadiene) and may include another hydrocarbon; block A content is 20-50%; the copolymer having a solution viscosity at 25 DEG C of 200-100,000 cps; and (3) 0.01-30% of a compound having in its molecule an unsaturated bond and a polar group, e.g. having affinity to the amido link in the polyamide (e.g. an unsaturated dicarboxylic acid or an hydride). <??>The composition is moldable and has good mechanical strength and solvent resistance.
