Thermoplastic resin compositions.

A thermoplastic resin composition containing (A) 1 to 99 % by weight of a modified polyphenylene ether comprising repeating units of the formula (1): in which R1 and R2 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 substituted by an aminomethyl group wherein X is a number average polymerization degree, and (B) 99 to 1 % by weight of a polyolefin which is modified with a compound having a functional group reactive with an amino group in a molecule, which composition is excellent in heat resistance, melt flowability, processability and impact resistance, and provides an article having good appearance and gloss.
