Abstract

Abstract A thermoplastic resin composition comprising (A) from about 10 to about 90% by weight of a hydroxyalkylated polyphenylene ether represented by formula (I): <IMAGE> (I) wherein A represents a residue of a polyphenylene ether from which a hydroxyl group is removed; and n represents an integer of from 1 to 10, and (B) from about 10 to about 90% by weight of a resin selected from a carboxyl-containing olefin resin, an epoxy-containing olefin resin, a hydroxyl-containing olefin resin, a polyamide resin, and a saturated polyester resin, provided that when (B) is the olefin resin, the hydroxyalkylated polyphenylene ether also can be represented by formula (II): <IMAGE> (II) wherein A is defined as above; X represents an oxygen atom or a nitrogen atom; R1 represents an alkylene group having from 1 to 12 carbon atoms; R2 and R3 each represents a hydrocarbon group having from 1 to 6 carbon atoms; s represents 1 when X is an oxygen atom, or 2 when X is a nitrogen atom; and t represents an integer of from 1 to 3.
