    • A process for making a thermoplastic resin composition which comprises a 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 R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 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 .eta..sub.sp/c of 0.40-0.58 deciliter/gram.
    • 一种制备热塑性树脂组合物的方法,其包括熔融并混合100重量份的聚苯醚(A)和0.01-5.0重量份的至少一种化合物(B),其在分子中包含(a)碳 - 碳双键或碳 - 碳三键,和(b)羧基,酸酐基,酰胺基,酰亚胺基,羧酸酯基,环氧基,氨基或羟基,在0.01%以上 相对于聚苯醚(A)为0.1重量%以上的自由基引发剂,所述聚苯醚(A)是通过至少一种由下式表示的酚化合物的氧化聚合得到的:其中R1,R2,R3, R 4和R 5表示氢原子,卤素原子,烃基或取代的烃基,条件是它们中的至少一个是氢原子,并且所述聚苯醚(a)具有降低的粘度eta sp / c 0.40-0.58分升/克。
