Disclosed herein is an ion conductive polymer comprising a unit represented by Formula (1) below:&#x2014;SO[NSO(M)]-&#x2003;&#x2003;(1) Further disclosed is an imide monomer represented by Formula (A) below:Z-SO[NSOM]-Z&#x2003;&#x2003;(A)

Ion conductive polymers and imide monomers

An electrolyte for electrochromic elements which comprises an electrolytic base material to conduct ions and charge-controlling substances contained in the electrolytic base material. The electrolytic base material is composed of a polar organic solvent and a supporting electrolyte and the charge-controlling substance is at least one of oxidizable substances and reducible substances. This electrolyte enables to produce durable electrochromic elements which can balance the charges in both electrodes and avoid a residual color or an uneven color of coloring materials.
