    • Disclosed is a copolymer represented by the following general formula (1): ##STR1## wherein R.sub.1 represents a group based on a polymer or a copolymer possessing electroconductivity and inducing coloration or discoloration on being oxidized or reduced, R.sub.2 and R.sub.3 represent independently a hydrogen atom or an alkyl group having 1 to 1,000 carbon atoms, A represents a group possessing polarity and exhibiting affinity for ions, and L and M are independently an integer of at least 1, providing that the total degree of polymerization is an integer in the range of 10 to 12,000. The copolymer may be a block copolymer or a random copolymer. This copolymer exhibits electrochromism and, therefore, is useful as a coloring-discoloring material which induces coloration or discoloration on being oxidized or reduced, particularly as an electrochromic substance used in an electrochromic display device.
