摘要：
Ethylene oxide was copolymerized with propylene oxide, epichlorohydrin or styrene oxide at various monomer feed compositions, using partially hydrolyzed organoaluminium compounds as catalysts. The copolymers obtained after doping with NaI form highly conductive polymeric electrolytes. Complex impedance measurements show relaxation semicircles much less depressed than in semicrystalline electrolytes based on poly(ethylene oxide). The maximum values of the room temperature conductivity for each kind of copolymer containing electrolytes are higher than those for the pristine poly(ethylene oxide)-NaI system. The highest value, equal to 2.6.10(-5) S/cm at 25-degrees-C, was found for poly(ethylene oxide-co-propylene oxide) containing 33 mol-% of propylene oxide monomeric units.
