  • Patent number: 10501626
    Abstract: Polyarylene sulfide compositions are described that exhibit high strength and flexibility. Methods for forming the polyarylene sulfide compositions 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.

  • Patent number: 8840976
    Abstract: VOC or compressed gas containment devices, such as polymer fuel tanks, are made from a polyoxymethylene polymer composition. The polymer composition contains a polyoxymethylene polymer that is directly or indirectly chemically attached to an impact modifier. In one embodiment, for instance, a coupling agent bonds the impact modifier to the polyoxymethylene polymer. In order to preserve the permeability of the polymer material when combined with the impact modifier, a polyoxymethylene polymer is used that contains a low level of low molecular weight constituents.

  • Patent number: 8709563
    Abstract: An electrical conduit that contains a jacket that defines a hollow passageway is provided. At least a portion of the jacket is formed from a thermoplastic composition that contains a polyarylene sulfide and fire-resisting system. Due in part to the specific nature and concentration of these components, the present inventors have discovered that the resulting thermoplastic composition may have a relatively high melting temperature, such as from about 200° C. to about 500° C.
