Abstract
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.
