POLYPHENYLENE SULFIDE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polyphenylene sulfide resin composition having remarkably excellent optic axis stability of a laser focus and balanced and excellently small flash-forming property. SOLUTION: The polyphenylene sulfide resin composition is produced by compounding a polyphenylene sulfide resin (A-1) with (B) 100 pts.wt. of an acid-cleaned polyphenylene sulfide resin (A-2) and (B') 10-60 pts.wt. of acetylene black under melting and kneading. The content of the acetylene black (B') is 0.2-3.5 pts.wt. based on 100 pts.wt. of total polyphenylene sulfide resin. COPYRIGHT: (C)2006,JPO&NCIPI
