Abstract
A thermoplastic resin composition comprising: PA1 (a) about 20 to 80% by weight of polyphenylene ether resin comprising at least one structural unit in its backbone represented by the formula: ##STR1## wherein (b) about 0.01 to 10% by weight of a modified aromatic hydrocarbon-formaldehyde resin produced by modifying an aromatic hydrocarbon-formaldehyde resin which is obtained by reacting alkyl benzene with formaldehyde, using a modifying agent reactive with its methylol group, methylene ether group, or acetal group; PA1 (c) about 2 to 30% by weight of a rubber-like polymer; and PA1 (d) about 20 to 80% by weight of a polyamide resin; and a method for its preparation.
