Abstract
A polyphenylene sulfide resin composition includes a polyphenylene sulfide resin (a) of 90 to 50% by weight and a polyphenylene sulfide resin (b) and/or a polyphenylene sulfide resin (c) of the total of 10 to 50% by weight blended with the polyphenylene sulfide resin (a), relative to the total of the polyphenylene sulfide resins (a) to (c) as 100% by weight, in which the polyphenylene sulfide resin composition has a change rate of viscosity of 1.5 times or less when the composition is heated at 320° C. for 5 hours.
Claims12
A polyphenylene sulfide resin composition that, in a molecular weight distribution measured in size exclusion chromatography,
- (i) has a peak top of a main peak in a molecular weight region of 10,000 to 1,000,000, and
- (ii) has a peak top of a subpeak in a molecular weight region of 100 to less than 10,000,
- (iii) wherein the area fraction of the subpeak is 1.0 to 20%;
- and that has a change rate of viscosity of 1.5 times or less when the composition is heated at 320° C. for 5 hours.
