Polyfether imide

Amorphous polymers are characterized by the following properties They are transparent and very often soluble in common organic solvents at room temperature. The following amorphous polymers have gained industrial importance as thermoplastic materials polyfvinyl chloride), polystyrene, polyfmethyl methacrylate), ABS-polymers, polycarbonate, cycloolefine copolymers, polysulfone, poly( ether sulfone), polyfether imide). 

PPE exhibits a high dielectric strength. Thus, it can be used as a polymeric electret. Neat PPE shows an excellent charge storage behavior, which is better than that of cellular poly(propylene) and polyfether imide).

Radiation-induced graffing is a method widely investigated for the preparation of AEMs. Nevertheless, the success of these membranes is limited. When radiation-induced grafting is practiced at a large scale, the amount of electrical power required for production is on the one hand very expensive and, on the other, physically impracticable. The introduction of cationic moieties into a polymer by chemical modification is widely investigated. Membranes based on styrene, polyfether imide), or polysulfone suffer from the problem that their preparation makes use of...
