ABSTRACT:
A thermoplastic resin composition containing (A) 100 parts by weight of at least one modified polyphenylene ether selected from the group consisting of (A1) a modified polyphenylene ether having repeating units of the formula (1): ##STR1## in which R.sub.1 and R.sub.2 are, independently from each other, a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms and having a number average polymerization degree of 20 to 1200, in which 0.02/X to 1/X of methyl groups at the 2- and/or 6-positions of phenylene group are modified to an aminomethyl group in which X is a number average polymerization degree and (A2) a modified polyphenylene ether comprising polyphenylene ether to which an amino group-containing monomer is graft polymerized, and (B) 0.1 to 70 parts by weight of an epoxy group-containing ethylene copolymer comprising (a) 50 to 99% by weight of ethylene units, (b) 0.1 to 30% by weight of unsaturated carboxylic acid diglycidyl ester units or unsaturated glycidyl ether units and (c) 0 to 50% by weight of ethylenically unsaturated ester compound units, which composition has improved molding processability and impact resistance.
