Electrochemical polymerization of pyrrole with water-soluble polymeric electrolytes

Summary form only given. We report the dehalogenative polymerization of methyl 1, 4-dichloro- benzoate (MDCB) and methyl 2,5-dichlorothiophene carboxylate (MDCTC), and its hydrolysis to poly(sodium paraphenylene carboxylate) (PSPC) and poly(sodium thiophene-3-carboxylate) (PSTC) that are useful for the electrochemical polymerization of pyrrole. The degree of polymerization of PMPC and PMTC were 40 and 18, respectively. These polymers were soluble in water. Electrochemical polymerization of pyrrole was carried out in water with PSPC and PSTC, and the conductivities of polypyrrole films were 1.3 and 0.24 S/cm, respectively. By using PSPC and PSTC gave conducting films, it is suggested that PSPC and PSTC are interesting polymeric electrolytes.
