Publication number: 20230151209Abstract: Described herein are polymer compositions including a liquid crystal polymer (“LCP”) and 1 weight percent (“wt. %”) to 25 wt. % of a semi-aromatic, semi-crystalline polyester, relative to the total weight of the LCP and semi-aromatic, semi-crystalline polyester. It was surprisingly discovered that polymer compositions including an LCP in conjunction with a semi-aromatic, semi-crystalline polymer could be melt-extruded into desirable films, as opposed to corresponding polymer compositions. It was further surprisingly discovered that the polymer compositions described herein had improved mechanical performance (tensile strength and tensile elongation), relative to corresponding polymer compositions. Still further, the polymer compositions also unexpectedly had reduced (Tm-Tc) relative to corresponding polymer compositions and, therefore, provided faster cycle times for molded articles formed from the polymer compositions.Type: ApplicationFiled: March 10, 2021Publication date: May 18, 2023Applicant: SOLVAY SPECIALTY POLYMERS USA, LLCInventors: Xiaoling Xu, Glenn P.

Publication number: 20220380546Abstract: 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.Type: ApplicationFiled: October 12, 2020Publication date: December 1, 2022Applicant: SOLVAY SPECIALTY POLYMERS USA, LLCInventors: Matthew Nielsen, Stéphane Jeol
