ABSTRACT PROCESS FOR MAKING A THERMOPLASTIC RESIN COMPOSITION 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 com- pound represented by the formula: Image wherein R1, R2, R3, R4 and R5 represent a hydrogen atom, a halogen atom, a hydrocarbon or a substituted hydro- carbon group, with a proviso that at least one of them is a hydrogen atom, and said polyphenylene ether (A) having a reduced viscosity ?sp/c of 0.40 - 0.58 deciliter/gram.
