Abstract
Poly(ether urethane) cationomers based on poly(oxytetramethylene), 4,4 '-bibenzyldiisocyanate, N-methyldiethanolamine as chain extender, and acrylic acid/poly(acrylic acid) as quaternization agent were synthesiz ed. Pyrrole (15 wt.-%) was polymerized in films of the ionomer contain ing CuCl2. The films were characterized by dynamic mechanical analysis , thermogravimetry and differential scanning calorimetry. The electric conductivity of the film without polypyrrole is 7.5 . 10(-12) Omega(- 1)cm(-1), while incorporation of polypyrrole increases the conductivit y to 4.5 . 10(-6) Omega(-1) cm(-1).
