|Title:||POLYPHENYLENE SULFIDE HAVING LOW CHLORINE CONTENT, PREPARATION METHOD THEREFOR, RESIN COMPOSITION, AND FORMED BODY|
A polyphenylene sulfide having a low chlorine content, a preparation method therefor, a resin composition, and a formed body; the polyphenylene sulfide having a low chlorine content is obtained by capping 4-thiophenyl-thiophenol. The preparation method of the polyphenylene sulfide uses a sulfocompound, an alkaline substance and p-dichlorobenzene as raw materials, a fatty acid as a polycondensation additive, and 4-thiophenyl-thiophenol (PTT) as a terminal group modifier for condensation polymerization. Product yield is high and cost is low; the obtained polyphenylene sulfide product has low chlorine content, and also has excellent flowability and heat resistance; thus, the product can satisfy the use requirements for low chlorine and high flowability in the electronic and electric trade.
