Abstract
Abstract Polymers having repeat units represented by formula (Ia) in the main chain thereof, ##STR1## wherein Ar represents an aromatic conjugated group, and n is 10 or more, and a method of producing polymers having repeat units of general formula (I), ##STR2## wherein Ar represents an aromatic conjugated group, and X 1 and X 2 each represent hydrogen or halogen when the bond between the two carbon atoms is a double bond, and when the bond is a triple bond, neither X 1 nor X 2 exist by the electrochemical reduction of a monomer having general formula, Z.sup.1 -Ar-Z.sup.2 (II), wherein Ar is the same as that defined in the above formula (I), and Z 1 and Z 2 each represent a methyl halide, are disclosed. These polymers are semiconductive or electroconductive and can be used as an active material of the electrodes of organic secondary batteries.
