    • A process for producing a polyphenylene sulfide resin composition includes melt-kneading about 99 to about 60 wt % of a polyphenylene sulfide resin (a) and about 1 to about 40 wt % of a polyamide resin (b), and about 0.1 to 10 parts by weight of a compatibilizing agent (c) per 100 parts by weight in total of the polyphenylene sulfide resin (a) and the polyamide resin (b), using a double screw extruder with two or more kneading portions at a temperature of the range from a melting peak temperature of the polyphenylene sulfide resin+10° C. to a melting peak temperature of the polyphenylene sulfide resin+70° C., wherein the polyamide resin (b) is excluded nylon 46 and has a relative viscosity of 1.5 or more measuring in concentrated sulfuric acid at a concentration of 1% and at 25° C., wherein the compatibilizing agent (c) is a compound having one or more types of groups selected from epoxy groups, amino group and isocyanate group, and wherein the resin composition has a morphology that the polyphenylene sulfide resin (a) in the resin composition forms a sea phase while the polyamide resin (b) in the resin composition forms an island phase, and the number average dispersed particle size of the polyamide resin (b) is kept at less than about 500 nm after the resin composition is melted and allowed to reside at 300° C. for 30 minutes.
    • 聚苯硫醚树脂组合物的制造方法包括熔融捏合约99〜约60重量%的聚苯硫醚树脂(a)和约1〜约40重量%的聚酰胺树脂(b),以及约0.1〜10重量份 的相容剂(c)相对于聚苯硫醚树脂(a)和聚酰胺树脂(b)的总计100重量份,使用具有两个或更多个捏合部分的双螺杆挤出机,温度范围为 聚苯硫醚树脂的熔融峰值温度+10℃至聚苯硫醚树脂的熔融峰温度+ 70℃,其中聚酰胺树脂(b)不含尼龙46,相对粘度为1.5以上 在浓硫酸浓度为1%和25℃下测量,其中相容剂(c)是具有一个或多个选自环氧基,氨基和异氰酸酯基团的基团的化合物,并且其中树脂 组成具有形态学 树脂组合物中的聚苯硫醚树脂(a)形成海相,而树脂组合物中的聚酰胺树脂(b)形成岛相,并且聚酰胺树脂(b)的数均分散粒径保持在较小 在树脂组合物熔融之后约为500nm,并在300℃下放置30分钟。
