Thermoplastic resin composition

A thermoplastic resin composition which comprises:

• (A) 100 parts by weight of a composition comprising 95-5% by weight of a polyphenylene ether obtained by oxidation polymerization of at least one phenol compound represented by the following formula:
• ##STR7## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 which may be identical or different, each represents a hydrogen atom, a halogen atom, a hydrocarbon radical or a substituted hydrocarbon radical and at least one of them is a hydrogen atom, and 5-95% by weight of a thermoplastic polyester,
• (B) 0.1-30 parts by weight of (i) a natural or synthetic polymer material elastic at room temperature, or (ii) a modified natural or synthetic polymer material elastic at room temperature;
• (C) 0.01-10 parts by weight of at least one amino resin, wherein the amino resin (C) is represented by the following formulas (I), (II), or (III):
• ##STR8## wherein R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 each represents a hydrogen atom, an alkyl group, an aryl group or a substituent denoted by the formula (I'):
• --CH.sub.2 --O--R.sub.12, wherein R.sub.12 represents a hydrogen atom, an alkyl group of 1-10 carbon atoms or a cycloalkyl group of 10 carbon atoms or less, and at least one of R.sub.6 -R.sub.11 is a substituent denoted by the formula (I'), ##STR9## wherein R represents a hydrogen atom, an alkyl group, an alkoxy group or an aryl group excluding amino group, R.sub.13, R.sub.14, R.sub.15, and R.sub.16, each represents a hydrogen atom, an alkyl group, an aryl group or a substituent represented by the above-mentioned formula (I') and at least on of R.sub.13 -R.sub.16 is a substituent represented by the formula (I');
• and ##STR10## wherein R.sub.17, R.sub.18, R.sub.19, and R.sub.20, each represents a hydrogen atom, an alkyl group, an aryl group or a substituent represented by the above-mentioned formula (I') and at least one of R.sub.17 -R.sub.20 is a substituent represented by the formula (I').
