Described herein are poly(arylene sulfide) ('PAS') polymers (PASP) including recurring units formed from selected dihalofluorene monomers. Surprisingly, at relative low dihalofluorene monomer concentrations, the PAS polymers (PASP) have significantly increased glass transition temperatures (“T”) and impact performance, relative to analogous PAS homopolymers and PAS polymers (PASP) including recurring units formed from 4,4'-dibromobiphenyl (“DBBP”). Simultaneously, the PAS polymers (PASP) also retain high elastic modulus. Furthermore, the PAS polymers (PASP) are free of recurring units formed from polyhalogenated biphenyls (e.g. DBBP and polychlorinated biphenyls) and, therefore, are not currently subject to restrictive governmental regulation. Due at least in part to the excellent thermal (T, Tand T) and impact properties of the PAS polymers (PASP), the PAS polymers (PASP) and PAS polymer compositions can be desirably incorporated into wide variety of articles including, but not limited to, automotive articles, electrical and electronic articles, articles for aerospace and oil and gas articles.

Poly(arylene sulfide) polymers and corresponding polymer compositions and articles

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 (“T”). 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.
