Polyimide fibers with kidney-shaped cross-sections are prepared by a continuous, integrated approach, starting from a polyamic acid solution prepared by reacting an aromatic dianhydride with an aromatic diamine. PAA nascent fibers with kidney-shaped cross-sections are obtained by adopting a spinneret having circular orifices under wet spinning process. The kidney-shaped cross-sections are obtained by varying the processing condition, including spinning speed, coagulation bath composition, coagulation temperature, and depth of coagulation bath. After washing and drying, polyamic acid nascent fibers are converted to polyimide fibers with kidney-shaped cross-sections under thermal curing. The integrated preparation methods are suitable for mass industrial production.

  • Publication number: 20140242385
    Abstract: A fiber formed from a polymer composition that comprises a liquid crystalline polymer and an aromatic amide oligomer is provided. The present inventors have discovered that the oligomer can act as a flow aid for the polymer, which can provide a variety of different benefits. For example, the use of the oligomer during polymerization can lower the melt viscosity of the polymer as it is formed. This enables the formation of high molecular weight polymers that do not solidify within the reactor vessel. The formation of high molecular weight polymers during melt polymerization can, in turn, provide a variety of benefits, such as allowing for higher molecular weight polymers to be formed through additional processing (e.g., solid state polymerization) than conventionally possible, as well as enhancing the melt strength of the polymer composition and thereby aiding in the fiber formation process.
