    摘要： A blend of a polyolefin and a poly(alkyl vinyl ether) can be blended at elevated temperature to form a copolymer of the polyolefin and poly(alkyl vinyl ether). The resulting composition is useful as a compatibilizer, as a more water permeable substrate than the polyolefin, and as a photo-degradable material.

    摘要： Side-chain crystallizable (SCC) polymers are useful in various medical applications. In certain applications, heavy atom containing side-chain crystallizable polymers (HACSCCP's) are particularly useful. An example of a HACSCCP is a polymer that comprises a main chain, a plurality of crystallizable side chains, and a plurality of heavy atoms attached to the polymer. In certain configurations, the heavy atoms are present in an amount that is effective to render the polymer radiopaque. A polymeric material that includes an HACSCCP may be fabricated into a medical device useful for at least partially occluding a body cavity. For example, such a medical device may be an embolotherapy product. A polymeric material that includes a SCC polymer may also be fabricated into other medical devices, such as stents.

    摘要： Sulfonated polymers are made by the direct polymerization of a sulfonated monomer to form the sulfonated polymers. The types of sulfonated polymers may include polysulfones or polyimides. The sulfonated polymers can be formed into membranes that may be used in proton exchange membrane fuel cells or as ion exchange membranes. The membranes formed from the sulfonated polymers exhibit improved properties over that of Nafion®. A heteropoly acid may be added to the sulfonated polymer to form a nanocomposite membrane in which the heteropoly acid is highly dispersed. The addition of a heteropoly acid to the sulfonated polymer increases the thermal stability of the membrane, enhances the conductivity above 100° C., and reduces the water uptake of the membrane.

    摘要： A family of polymers having pendent sulfonate moieties connected to polymeric main chain phenyl groups are described. These polymers are prepared by the steps of polymerization (using a monomer with a phenyl with an alkoxy substitution), deportation by converting the alkoxy to a hydroxyl, and functionalization of the polymer with a pendant sulfonate group. As an example, sulfonated poly(arylene ether sulfone) copolymers with pendent sulfonic acid groups are synthesized by the direct copolymerization of methoxy-containing poly(arylene ether sulfone)s, then converting the methoxy groups to the reactive hydroxyl form, and finally functionalizing the hydroxyl form with proton-conducting sites through nucleophilic substitution. The family of polymers may have application in proton exchange membranes and in other applications.

    摘要： A low cost method of fabricating bipolar plates for use in fuel cells utilizes a wet lay process for combining graphite particles, thermoplastic fibers, and reinforcing fibers to produce a plurality of formable sheets. The formable sheets are then molded into a bipolar plates with features impressed therein via the molding process. The bipolar plates formed by the process have conductivity in excess of 150 S/cm and have sufficient mechanical strength to be used in fuel cells. The bipolar plates can be formed as a skin/core laminate where a second polymer material is used on the skin surface which provides for enhanced conductivity, chemical resistance, and resistance to gas permeation.
