ELECTROCHEMICAL POLYMERIZATION OF PYRROLE WITH WATER-SOLUBLE POLYMERIC ELECTROLYTE

The dehalogenative polymerization of methyl 2,5-dichlorothiophene carb oxylate (MDCTC) and methyl 2,5-dichlorobenzoate (MDCB) gave poly(methy l thiophene-3-carboxylate) (PMTC) and poly(methyl phenylene carboxylat e)(PMPC), respectively. Hydrolysis of PMTC and PMPC produced poly(sodi um thiophene-3-carboxylate) (PSTC) and poly(sodium phenylene carboxyla te) (PSPC), respectively. Both these polymers were soluble in water. T he electrochemical polymerization of pyrrole (PY) using PSTC and PSPC gave conducting polypyrrole (PPY) films. It is suggested that PSTC and PSPC as water-soluble polymeric electrolytes were useful for the elec trochemical polymerization of PY.
