Patent number: 10829595Abstract: 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.Type: GrantFiled: February 6, 2018Date of Patent: November 10, 2020Assignee: SOLVAY SPECIALTY POLYMERS USA, LLCInventors: Hong Chen, Peter Mushenheim, Lee Carvell, Erik Nelson, Charles R.
