Patent number: 11840606Abstract: Described here are blocky PEEK copolymers and corresponding synthesis methods. It was surprisingly found that synthesis of blocky PEEK copolymers in a non-solvent environment with respect to PEEK produced blocky PEEK copolymers with high degrees of functionalization and crystallinity. The blocky PEEK copolymers had an increased blocky structure, relative to corresponding PEEK copolymer synthesized with other known methods. Moreover, membranes formed from the blocky PEEK polymers are particularly desirable in fuel cell applications. For example, the membranes formed from the blocky PEEK polymers had surprisingly large ion conductivities as well as significantly improved chemical and thermal resistance, at least in part, to the improved functionalization and crystallinity.Type: GrantFiled: December 15, 2021Date of Patent: December 12, 2023Assignees: SOLVAY SPECIALTY POLYMERS ITALY S.P.A., VIRGINIA TECH INTELLECTUAL PROPERTIES, INC.Inventors: Kelly D.

Publication number: 20230242759Abstract: Described herein are polymer compositions (PC) including a polyamide (PA) and a poly(arylene sulfide) (PASP). The polyamide (PA) is a semi-aromatic polyamide derived from the polycondensation of an aliphatic diamine, a bis(aminoalkyl)cyclohexane, terephthalic acid, and, optionally, a cyclohexanedicarboxylic acid. It was surprisingly discovered that semi-aromatic polyamides derived from the cycloaliphatic diamine bis(aminoalkyl)cyclohexane or the specific combination of the cycloaliphatic diamine bis(aminoalkyl)cyclohexane and the cycloaliphatic dicarboxylic acid cyclohexanedicarboxylic acid provided for polymer compositions (PC) having improved retention of mechanical properties (e.g. tensile modulus and tensile strength) after aging in aqueous polyol solutions. It was also surprisingly discovered that incorporation of a nucleating agent in the polymer composition (PC) provided for significantly improved tensile strength retention after aging.Type: ApplicationFiled: May 5, 2021Publication date: August 3, 2023Applicant: SOLVAY SPECIALTY POLYMERS USA, LLCInventors: Matthew R.

Publication number: 20230183454Abstract: Described herein are electrical articles comprising a polyamide (PA). As explained in detail below, the polyamide (PA) is a semi-aromatic polyamide derived from the polycondensation of an aliphatic diamine, terephthalic acid, and a bis(aminoalkyl)cyclohexane or a cyclohexanedicarboxylic acid. It was surprisingly discovered that incorporation of the cycloaliphatic diamine bis(aminoalkyl)cyclohexane or the cycloaliphatic dicarboxylic acid cyclohexanedicarboxylic acid into the polyamide provided for polymer compositions (PC) having significantly improved comparative tracking index (“CTI”) retention after heat aging, relative to analogous polyamides derived from only the aliphatic diamine and terephthalic acid. Due at least in part to the improved CTI retention, the polyamides (PA) can be desirably incorporated into articles that, during use, are exposed to elevated temperatures and benefit from high CTI performance.Type: ApplicationFiled: May 7, 2021Publication date: June 15, 2023Applicant: SOLVAY SPECIALTY POLYMERS USA, LLCInventors: Clay Plavcan, David McIlroy, Stéphane Jeol, Lee Carvell
