摘要： An ionomer and a process for forming the ionomer such that the ionomer has (1) low equivalent weight; below 950, preferably between 625 and 850, and most preferably between about 700 and about 800; and (2) high conductivity, (greater than 0.15 S/cm). In an alternative embodiment, the ionomer has (1) low equivalent weight; below 950, preferably between 625 and 850, and most preferably between about 700 and about 800; and (2) acceptably low hydration, (less than about 75 weight percent). These ionomers are adapted to be processed into thin films that have acceptable physical stability. They are thus extremely well-suited for low humidity or high temperature fuel cell applications.

摘要： An aqueous microemulsion polymerization procedure is described in which very small colloidal melt-processible fluoropolymer particles are produced from at least one gaseous monomer and optionally TFE. The polymerization procedure involves forming a microemulsion of at least one liquid organic compound; adding at least one gaseous free-radical polymerizable monomer to the microemulsion; and initiating polymerization by adding a free-radical initiator to the mixture.

摘要： The present invention provides and employs a very thin yet highly light reflective material for use in providing diffuse reflectivity of light, especially in tightly confined applications such as in laptop computer displays. The present invention uses an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils combined with a coating or filler of material having a high index of refraction, such as titanium dioxide. The material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible and infrared light. Additionally, the material of the present invention provides many properties that have been previously unavailable in thin, highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at very thin cross-sections.

摘要： An improved elastomeric material is described comprising an essentially noncross-linkable amorphous copolymer of tetrafluoroethylene (TFE) and perfluoromethyl vinyl ether (PMVE) which is both a thermoplastic and exhibits exceptional mechanical properties. This material is particularly suitable for use in ultra-clean environments, and particularly for use in an implantable device, since it does not contain contaminants that previous thermoset TFE/PMVE copolymers have required. Among the improved properties of the present invention are excellent biocompatibility, high matrix tensile strength, high clarity, high abrasion resistance, high purity, adequate elasticity, and ease of processing due to the thermoplastic, and noncross-linkable structure of the copolymer. The material of the present invention is also a high strength bonding agent particularly suited for bonding porous PTFE to itself or to other porous substances at room or elevated temperatures.
