  • Publication number: 20240343963
    Abstract: Polymer compositions are provided, and articles made therefrom. The polymer compositions comprise from 25 to 50 wt. % of a thermoplastic polymer; from 10 to 45 wt. % of a thermally conductive filler; from 15 to 30 wt. % of an electrically conductive carbon fiber; and less than 5 wt. % additives. The polymer composition is substantially free of glass fibers. The polymer compositions described herein surprisingly exhibit significantly improved thermal conductivity relative to analogous polymer compositions in which the carbon fiber is replaced by glass fiber. Further, even though carbon fiber has a significantly higher electrical conductivity relative to glass fiber, the polymer compositions exhibit no appreciable loss of volume resistivity relative to analogous polymer compositions in which carbon fiber is replaced by glass fiber.

  • Patent number: 12110366
    Abstract: Described herein are polyamide polymers having improved glass transition temperatures (“Tg”) and relatively small values of Tm?Tg, where Tm is the melting temperature of the polyamide polymer. The polyamide polymers are semi-aromatic, semi-crystalline polyamide polymers that include recurring units formed the polycondensation of (1) a linear aliphatic diamine and a cycloaliphatic diamine with (2) an aromatic dicarboxylic acid. Due at least in part to the improved Tg, the polyamide polymers can be desirably incorporated into application settings including, but not limited to, mobile electronic devices, automotive, aerospace, building and construction, oil and gas, industrial, electrical and electronics, consumer goods, medical and healthcare. Furthermore, the polyamide polymers have relatively small values of Tm?Tg and, therefore, articles including the polyamide polymers can be more efficiently produced due to relatively small cycle times.

  • Patent number: 11999825
    Abstract: Described herein are end-capped poly(aryl ether sulfone) (“PAES”) polymers and corresponding synthesis methods. The end-capped PAES polymers are end-capped by functionalizing a PAES polymer with a halophthalic diialkyl ester end-capping agent. It was surprisingly discovered that the resulting dialkyl phthalate end-capped PAES polymers could be synthesized with significantly improved end-capping conversion rates, relative to end-capped PAES polymers directly functionalized with traditional phthalic anhydride end-capping agents. It was also surprisingly found that by heating the isopropyl phthalate end-capped PAES polymers, the polymers could be converted to the corresponding phthalic anhydride end-capped PAES polymers, yielding a more efficient synthetic route to phthalic anhydride end-capped PAES polymers.

  • Patent number: 11840606
    Abstract: 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.

  • Publication number: 20230242759
    Abstract: 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.
