    Abstract: Flowlines for use in oil and gas applications are described. The flowlines include a barrier layer that includes polyarylene sulfide composition that exhibits high strength and flexibility characteristics. Methods for forming the flowlines are also described. Formation methods include dynamic vulcanization of a polyarylene sulfide composition that includes an impact modifier dispersed throughout the polyarylene sulfide. A crosslinking agent is combined with the other components of the composition following dispersal of the impact modifier throughout the composition. The flowlines can include production fluid flowlines, supporting fluid flowlines, bundled flowlines, etc. and can be utilized as risers, pipelines, jumpers, and the like.

    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.
