Abstract:
Ionic conduction material comprising at least one cross-linked polymer obtained by anionic polymerization initiation followed by cationic cross-linking, the polymer being derived at least from a monomer having the general formula:(A)nQ(Y)p whereinQ represents a bond, â€”COâ€”, â€”SO2, or an organic radical of n+p valence which is non reactive towards reagents initiating anionic-or cationic polymerization, said organic radical being selected from alkyl, alkylaryl, arylalkyl, optionally comprising oxa or aza substituents, and comprising from 1 to 30 carbon atoms; A represents a radical which is reactive in anionic polymerization; Y represents a radical which is reactive in cationic polymerization and non-reactive toward agents initiating anionic polymerization, n varies between 1 and 3; and p varies between 1 and 6; and at least one salt Mn+Xnâˆ’, Mn+ being an inorganic, organic or organometallic cation of charge n, and Xâˆ’ being a monovalent anion and wherein two or more Xâˆ’ can be linked together with covalent chains or chains belonging to a polymer chain.
