Abstract
Described herein are poly(arylene sulfide) (“PAS”) polymers (PASP) including recurring units formed from a dihalocarbazole containing monomer. It was surprisingly found that such monomers could be incorporated into PAS polymers at desirable concentrations to provide improved amine content. Additionally, it was surprisingly found that, relative to PAS homopolymers and PAS polymers incorporating recurring units with primary amines, the PAS polymers (PASP) described herein and increased glass transition temperatures (“Tg”). The PAS polymers (PASP), and PAS polymer compositions, can be desirably incorporated into wide variety of articles including, but not limited to, automotive articles and oil and gas articles.
