  • Patent number: 9353263
    Abstract: A thermoplastic composition for use in a fine pitch electrical connector is provided. The thermoplastic composition contains a liquid crystalline polymer and a plurality of fibers. The volume average length of the fibers in the thermoplastic composition is selectively controlled according to the present invention so that it is within a certain range, such as from about 80 to about 250 micrometers. The fibers also have a narrow length distribution. That is, at least about 70% by volume of the fibers have a length within a certain range. Through the use of a liquid crystalline polymer and fibers of a certain weight average length and narrow length distribution, the present inventors have discovered that the resulting thermoplastic composition is able to achieve a desirable combination of strength and flowability, which enables it to be uniquely suited for the walls of a fine pitch connector.

  • Patent number: 9284664
    Abstract: Disclosed are polymeric additives for concrete formed of a polyoxymethylene (POM) copolymer, POM copolymers can be utilized to form fibrous additives for concrete, i.e., microfibers and/or macrofibers. The POM copolymers can include one or more chemical groups, e.g., end groups and/or pendant groups that can increase the polarity of the POM and increase the hydrophilicity of the formed fibers, which can improve miscibility of the fibers in wet concrete. Chemical groups of the POM copolymers can bond with components of the concrete or can hydrolyze to form groups that can bond with components of the concrete, e.g., form covalent or noncovalent (e.g., electrostatic or ionic) bonds with one or more components of the concrete binder.

  • Patent number: 9284435
    Abstract: A liquid crystalline polymer composition having a reduced tendency to create a static electric charge during a molding operation is provided. More particularly, the composition contains an ionic liquid that is distributed within a liquid crystalline polymer matrix. In addition to being electrically conductive, the ionic liquid can exist in liquid form during melt processing, which allows it to be more uniformly blended within the liquid crystalline polymer matrix. This improves electrical connectivity and thereby enhances the ability of the composition to rapidly dissipate static electric charges from its surface.
