    • Disclosed is a copolymer represented by the following general formula (1):

      wherein R₁ represents a group based on a polymer or a copolymer possessing electroconductivity and inducing coloration or discoloration on being oxidized or reduced, R₂ and R₃ 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.
    • 公开了一种共聚物由下述通式(1): worin R1 darstellt基于聚合物或共聚物波塞唱的导电性和诱导上被氧化或还原着色或变色的基团,R2和R3表示unabhängig氢原子 或具有1至1000个碳原子烷基的,A darstellt一组波塞唱极性和离子参展亲和力,而L和M是unabhängig到至少为1的整数,提供没有聚合的总度在该范围内的整数 10至12000。 该共聚物可以是嵌段共聚物或无规共聚物。 此共聚物呈现电致变色的,因此,是为诱导上被氧化或还原着色或变色,特别是作为电致变色在电致变色显示装置中使用的物质的着色变色材料是有用的。
