摘要: The present invention relates to a powdered material (M) containing at least one poly(arylene sulfide) (PAS) polymer, comprising recurring units p, q and r according of formula (I), (II) and (III): wherein np, nq and nr are respectively the mole % of each recurring units p, q and r; recurring units p, q and r are arranged in blocks, in alternation or randomly; 1%≤(nq+nr)/(np+nq+nr)≤12%; nq is ≥0% and nr is ≥0%; j is zero or an integer varying between 1 and 4; R1 is selected from the group consisting of halogen atoms, C1-C12 alkyl groups, C7-C24 alkylaryl groups, C7-C24 aralkyl groups, C6-C24 arylene groups, C1-C12 alkoxy groups, and C6-C18 aryloxy groups.

摘要: 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.

摘要: 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 (“Tg”) 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 (Tg, Tc and Tm) 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.
