Abstract: Electrically conductive polymers containing repeat units derived from five-membered aromatic heterocyclic monomers substituted, in the 3 position relative to the heteroatom, by an ether-type substituent linked to the heterocyclic ring by an alkylene radical containing at least two carbon atoms. The invention also relates to certain monomers enabling the above-mentioned conductive polymers to be obtained.

Abstract: A poly[(3-pyrrolyl)acetic acid] is here disclosed which is represented by the formula (I) ##STR1## wherein n is an integer of 2 or more. This polymer can be prepared by subjecting (3-pyrrolyl)acetic acid to electrolytic oxidation polymerization in the presence or absence of a salt. The polymer can be used as a pH sensor in which electrical properties change in accordance with a pH. Furthermore, it can also be used as electrodes for a secondary battery in which a cation transport electrolyte is used.

Abstract: There is provided a 3-substituted polypyrrole represented by the general formula (I) ##STR1## wherein R is an alkyl group having 1 to 5 carbon atoms, m is an integer of from 1 to 20, and n is an integer of 2 or more.
