Abstract
The invention provides a polyphenylene sulfide resin composition which comprises polyphenylene sulfide resin and a deformed cross-section glass fiber, wherein the chlorine content of the polyphenylene sulfide resin composition is equal to or lower than 1,000 ppm. The obtained polyphenylene sulfide resin composition is excellent in flowability, toughness and rigidity. The invention further provides a molding prepared from the polyphenylene sulfide resin composition and a manufacturing process for the polyphenylene sulfide resin composition. The polyphenylene sulfide resin composition is particularly suitable for products for forming frames of a portable computer, a mobile phone and a portable electronic device.
