Studies Toward Highly Fluorinated Polyphenylenes by Diels-Alder Polymerization
… (DAPPs) are chemically and thermally stable polymers, used for dielectric resins, gas separation membranes, and fuel cell proton exchange membranes. Highly fluorinated DAPPs are expected to have better thermal stability and chemical resistance, higher glass transition temperatures, …

Synthesis and Characterization of High Performance Polymers for Gas Separation Membranes
… and characterization of high performance polymers, especially polyimides, polybenzoxazoles and polybenzimidazoles for gas separation applications. An abundance of monomers and novel polymers were synthesized and fabricated into membranes. Thermally rearranged polybenzoxazoles and their …

FABRICATION OF FUNCTIONAL NANOSTRUCTURED POLYMERS BASED ON THERMOTROPIC AND LYOTROPIC LIQUID CRYSTALS DERIVED FROM SUSTAINABLE RESOURCES
… offer a route to achieve nanostructured polymers, a promising alternative to traditional nanostructured inorganic materials and block copolymers. LC mesophases can spontaneously form monodisperse nanostructures and their self-assembly can be precisely controlled to yield well-organized …

High Temperature Polymers for Proton Exchange Membrane Fuel Cells
… H2/air PEM fuel cells. The need for thermally stable polymers immediately suggests the possibility of heterocyclic polymers bearing appropriate ion conducting sites. Accordingly, monomers and random disulfonated poly(arylene ether) copolymers containing either naphthalimide, benzoxazole or …
