Process for making a thermoplastic resin composition
First Claim
1. A process for making a thermoplastic resin composition which comprises melting and mixing at a temperature of 240°
- -350°
C. 5-95 parts by weight of polyamide and 95-5 parts by weight of a polyphenylene ether composition,said polyphenylene ether composition being obtained by melting and mixing 100 parts by weight of polyphenylene ether (A), 0.01-5.0 parts by weight of at least one compound (B) which contains in its molecule both (a) carbon-carbon double bond or carbon-carbon triple bond and (b) carboxyl group, acid anhydride group, acid made group, imide group, carboxylic acid ester group, epoxy group, amino group or hydroxyl group, and 1-40 parts by weight of rubber-like materials (C) in the presence of 0.01% or more and less than 0.1 % by weight of radical initiator based on the polyphenylene ether (A),said polyphenylene ether (A) being obtained by oxidation-polymerization of at least one phenol compound represented by the formula;
##STR4## wherein R1, R2, R3, R4 and R5 represent a hydrogen atom, a halogen atom, a hydrocarbon or a substituted hydrocarbon group, with a proviso that at least one of them is a hydrogen atom, and said polyphenylene ether (a) having a reduced viscosity η
sp/c of 0.04-0.58 deciliter/gram.

Abstract
A process for making a thermoplastic resin composition which comprises melting and mixing 100 parts by weight of polyphenylene ether (A) and 0.01-5.0 parts by weight of at least one compound (B) which contains in its molecule both (a) carbon-carbon double bond or carbon-carbon triple bond and (b) carboxyl group, acid anhydride group, acid amide group, imide group, carboxylic acid ester group, epoxy group, amino group or hydroxyl group in the presence of 0.01% or more and less than 0.1% by weight of radical initiator based on the polyphenylene ether (A),
said polyphenylene ether (A) being obtained by oxidation-polymerization of at least one phenol compound represented by the formula: ##STR1## wherein R1, R2, R3, R4 and R5 represent a hydrogen atom, a halogen atom, a hydrocarbon or a substituted hydrocarbon group, with a proviso that at least one of them is a hydrogen atom, and said polyphenylene ether (A) having a reduced viscosity ηsp/c of 0.40-0.58 deciliter/gram.
