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:
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.
一种制造热塑性树脂组合物的工艺,包括熔化和混合 100 份(重量)聚苯醚 (A) 和 0.01 - 5.0 重量份的至少一种化合物 (B),其分子中含有(a) 碳碳双键或碳碳三键和(b) 羧基、酸酐基、酸酰胺基、酰亚胺基、羧酸酯基、环氧基、氨基或羟基、
所述聚苯醚(A)由至少一种由式表示的苯酚化合物氧化聚合而得:
其中 R₁、R₂、R₃、R₄ 和 R₅ 代表氢原子、卤素原子、烃基或取代的烃基,但其中至少有一个是氢原子,所述聚苯醚 (A) 的还原粘度 ηsp/c 为 0.40 - 0.58 分升/克。
