    摘要： A process for preparing an electronically-conductive thermoplastic composition having at least two phases, which includes (A) combining an amorphous or semi-crystalline thermoplastic polymer or miscible blend of polymers with an electronically-conductive carbon under conditions sufficient to disperse the conductive carbon, thereby forming a mixture having at least one phase, with at least 60 percent of the carbon dispersed in a first phase which comprises at least 90 percent by weight of the mixture; and (B) combining the mixture obtained from step (A) with an amorphous or semi-crystalline thermoplastic polymer or miscible blend of polymers, at least a portion of which is immiscible in the first phase, thereby forming a composition having at least two phases. Compositions prepared by this process are sufficiently conductive to be useful for a variety of applications, such as structural materials for applications requiring electromotively-paintable substrates.

    摘要： This invention relates a composition useful for preparing a polyvinylidene fluoride polymer membrane containing (1) a polyvinylidene fluoride polymer, (2) glycerol monoacetate, glycerol diacetate, glycerol triacetate, or mixtures thereof, and (3) optionally glycerol, wherein the polyvinylidene fluoride polymer membrane prepared from the composition is useful for a membrane liquid separation process such as microfiltration, ultrafiltration, dialysis, or membrane stripping. In another aspect, this invention is an improved process for using the composition to prepare a polyvinylidene fluoride polymer membrane by forming a mixture of the composition, heating the mixture to a temperature at which the mixture becomes a homogeneous fluid, and extruding, molding, or casting the homogeneous fluid into a membrane. Another aspect of this invention relates to a polyvinylidene fluoride polymer membrane where the fabricated membrane contains glycerol monoacetate, glycerol diacetate, glycerol triacetate, or mixtures thereof, and optionally glycerol.
