A resin composition comprises a resin composition having a melt flow rate (MFR) of 0.01-5dg/min. and a melt tension (MT) of at least 4g, which composition comprises:
from 10 to 60 parts by weight of polyphenylene ether having an intrinsic viscosity [η] of from 0.35 to 0.75 dl/g, as measured in chloroform at 30°C;
from 90 to 40 parts by weight of polyamide having a relative viscosity (ηr) of at least 2.5 (as measured in 98%H₂SO₄ according to JIS K6810);
from 0.1 to 30 parts by weight, per 100 parts by weight of polyphenylene ether and polyamide, of rubber-like material;
from 0.01 to 30 parts by weight, per 100 parts by weight of polyphenylene ether, polyamide and rubber-like material, of a compatibilizing agent which is a chemical compound having (d1) a carbon-carbon double bond or a carbon-carbon triple bond, and (d2) a carboxyl group, acid anhydride group, acid amide group, imide group, carboxylate group, amino group, or hydroxyl group, or mixture thereof; and
from 0.01 to 30 parts by weight, per 100 parts by weight of polyphenylene ether, polyamide and rubber-like material, of melt tension modifier which is an organic compound containing an oxirane oxygen atom.
