Abstract:
1. Ionically conductive material comprising a statistical copolymer which comprises ethylene oxide units, —O—CH 2 —CHR—units wherein R is a substituent containing a reactive function which is cross-linkable by free radical process, R may vary from one unit to the other, and —O—CH 2 —CHR′—units, wherein R′ is a substituent containing no function which is cross-linkable by free radical process, R′ may vary from one unit to the other; and which has a polymolecularity index I=Mw/Mn lower than or equal to 2.2, a random distribution of the different monomer units and an average molecular mass in Mn number at least equal to 20,000.
