Abstract: Sheets having thicknesses of from 1000 to 10,000 microns which are useful for the production of thermoformed semi-crystalline articles are based on polyaryletherketones having viscosities at 360° C. of at least about 400 Pas at 100 s?1 as measured by parallel plate rheometer. The polyaryletherketones are in a pseudo-amorphous state in the thermoformable sheets.

Abstract: The present disclosure is directed to a gas phase adsorption device comprising a large annulus and a small annulus block wherein the small annulus block is concentrically positioned inside the large annulus block. The present disclosure is also directed to a method for the storage of gas.

Abstract: The invention relates to membranes formed from long chain branched fluoropolymers, and especially long chain branched homopolymers and copolymers of polyvinylidene fluoride such as KYNAR resins. The novel membranes retain all the advantages of a fluoropolymer membrane (excellent chemical resistance especially to strong acids and oxidizing agents, and good mechanical strength), and additionally offer improved permeability, improved strain hardening, and even better resistance to caustic attacks. The improvements are believed to be related to an improvement to the microstructure of the membranes, producing a more open structure due to the long chain branched fluoropolymers. Further improvements in the mechanical properties of the membranes can be induced by strain hardening.

Abstract: The present disclosure is directed to an immobilized media device and methods for making an immobilized media device. The present disclosure is also directed to methods for the separation of components of a media comprising filtering the media through an immobilized media device.

Abstract: Hollow fiber membranes having improved toughness and durability are prepared using a vinylidene fluoride polymer-containing component, such as Kynaro resins, having relatively low crystallinity. One aspect of the invention provides a membrane in the form of a fiber, wherein i) the fiber has a porous wall of a polymeric component enclosing a central hollow space extending the length of the fiber, ii) the polymeric component has a crystallinity as determined by wide angle x-ray diffraction of less than about 35%, iii) the polymeric component is comprised of at least one homopolymer or copolymer of vinylidene fluoride and iv) the membrane has an energy to break of at least about 0.5 J per square mm of membrane cross section.
