Abstract
The present invention provides a thermoplastic resin composition which is improved in compatibility between polyphenylene ether and polyamide and is excellent in processability and impact strength. This composition comprises: (A) 100 parts by weight of a composition comprising 95-5% by weight of a polyphenylene ether obtained by oxidation polymerization of one or more of phenol compounds represented by the following formula: ##STR1## (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 polyamide, PA0 (B) 0-30 parts by weight of an impact strength modifier, and PA0 (C) 0.01-10 parts by weight of an amino resin obtained by modifying with an alcohol an addition reaction product of formaldehyde and at least one compound selected from the group consisting of melamine, guanamine and urea.
