The copolymer described is a segmented copolymer consisting essentially of organic segments A which have a number i of reactive ends such that i is from 1 to 6 inclusive, and segments B which have a number j of reactive ends such that j is from 1 to 6 inclusive. The segments B have redox properties and each segment A is connected to at least one segment B by a group Y and vice versa, the group Y being an ether, thioether, secondary amine, tertiary amine, secondary amide, tertiary amide, imide, quaternary ammonium group, or a group having a carbon-carbon bond. The respective weighted molar mean of i and j is 2 or more. Application to electrochemical generators and electrochromic systems.
L'invention concerne des copolymères et leur utilisation pour l'élaboration de matériaux à conduction mixte. Un copolymère de l'invention est un copolymère segmenté constitué essentiellement par des segments organiques A qui ont un nombre i d'extrémités réactives tel que 1 <= i <= 6, et par des segments B qui ont un nombre j d'extrémités réactives tel que 1 <= j <= 6, caractérisé en ce que les segments B présentent des propriétés rédox, que chaque segment A est relié à au moins un segment B par un groupe Y et réciproquement, le groupe Y étant un groupe éther, thioéther, amine secondaire, amine tertiaire, amide secondaire, amide tertiaire, imide, ammonium quaternaire, ou un groupe comportant une liaison carbone-carbone, et en ce que la moyenne molaire pondérée respective de i et de j est supérieure ou égale à 2. Application: générateurs électrochimiques, systèmes électrochromes.
