METHOD FOR PREPARING COMB POLYMER AND USE THEREOF FOR FORMING SOLID ELECTROLYTE

The invention relates to a method for preparing a comb polymer comprising at least one step consisting of grafting a polycarbonate/polyester telechelomer bearing a free thiol function at one of its ends, in the para position of some of the pentafluorophenyl groups of the monomeric units of a PPFS-type polymer, said grafting involving a nucleophilic substitution reaction between the thiol function carried by the polycarbonate/polyester telechelomer and the fluorine atom in the para position of the pentafluorophenyl group. [0002] It further relates to the use of such a comb polymer for forming a solid electrolyte.
