The monomer consists of a polyether containing at least 3 ether units and pyrrole or thiophene units bonded to the ends of the chains of this polyether via, for each of these heterocycic compounds, either their carbon atoms in the 3,3'-positions of their heterocycles or, as regards more particularly the pyrrole groups, via their respective nitrogen atoms, the 2- and 2'-positions of these heterocycles being, however, free of all substitutions or, at the very most, substituted by easily removable groups (protective groups, for example). Application to the purification and recovery of metal ions such as radioactive silver.Type: GrantFiled: June 7, 1995Date of Patent: October 29, 1996Assignee: Electricite de France - Service NationalInventor: Olivier Leclerc

Patent number: 5561206Abstract: 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.Type: GrantFiled: April 3, 1995Date of Patent: October 1, 1996Assignees: Yoshida Kogyo K.K., Takakazu YamamotoInventors: Takakazu Yamamoto, Masaki Wakabayashi
