ABSTRACT:
(A) 10-70 parts by weight of a polyphenylene ether, a mixture of a polyphenylene ether and a polystyrene or a polyphenylene ether-styrene graft copolymer,
(B) 90-30 parts by weight of a mixture of (i) a thermoplastic aromatic copolyamide and/or an aromatic nuclear-hydrogenated copolyamide in an amount of 0.1-70% by weight of existing total polyamide and (ii) a thermoplastic aliphatic polyamide in a complementary amount of 99.9-30% by weight of existing total polyamide, and
(C) 0.01-30 parts by weight, based on 100 parts by weight of the above components (A) and (B) of, at least one compound selected from the group consisting of oxazoline and a compound having, in its molecule, (a) carbon-carbon double bond or a carbon-carbon triple bond and (b) at least one functional group selected from carboxyl group, acid anhydride group, amino group, acid amide group, imido group, epoxy group, carboxylate ester group, isocyanate group, methylol group, oxazolidine group and hydroxyl group.
This composition may further contain an impact strength modifier, namely, rubber-like material and/or modified rubber-like material.
