Abstract

Described here are polyphenylene sulfide ('PPS') polymers having significantly improved processability. It was surprisingly found that PPS polymers, terminated with specific end-capping agents in specific amounts, had significantly improved melt stability. Because of the significantly improved melt stability, the PPS polymers can be advantageously incorporated into melt processing techniques.
