System and method for reducing off-gassing of polyphenylene sulfide
摘要:
The techniques provide a system and a method of producing polyphenylene sulfide (PPS) polymer. The PPS polymer is produced by reacting a sulfur source and a dihaloaromatic compound in the presence of a polar organic compound in a polymerization mixture in a polymerization vessel. The PPS polymer is washed with a base to lower the oligomer content of the PPS polymer and thus the off-gassing during processing.
