Some polyurethane anionomers synthesized by a two-step substitution postreaction of urethane hydrogen atoms with CH 2 COONa groups were studied. The influence of ionic structures on the mechanical and electrical properties of polymers was followed. The carboxylated polyurethane anionomers were used

β¦ Synopsis
Preparation of a molecular-level composite of sulfonated polyurethane ionomer and polypyrrole (PUA-PPy) was performed by electrochemical polymerization of pyrrole in aqueous solution of polyurethane anionomer and was confirmed by compositional and Fourier transform infrared analysis. The effects of anionomer concentration and of electrochemical reduction process were followed, and it was forecasted that the composite could behave as a cation exchanger. Some results of thermal analysis were also presented.

An organic-inorganic composite was prepared by mixing silica emulsion with urethane acrylate anionomer (UAA) emulsion. The silica emulsion was prepared by sol-gel process, and stabilized by a steric stabilizer, polyvinyl pyrrolidone. UAA/silica composite film was made by an ultraviolet curing method
Through a chemical polymerization of pyrrole inside ultrahigh molecular weight polyethylene (UHMWPE) foam, a conducting polymer composite was obtained. To produce conductive polymer foams, successive imbibiting of reactives, FeCl 3 and pyrrole in tetrahydrofuran solutions, were carried out. The cond
