Copolymer of ethylene oxide and at least one substituted oxirane carrying a cross-linkable function, process for preparation thereof, and use thereof for producing ionically conductive materials |
摘要 |
The invention concerns a copolymer of ethylene oxide and at least one substituted oxirane carrying a cross-linkable function. The copolymer comprises ethylene oxide, -O-CH2-CHR- units in which R is a substituent containing a reactive function which is cross-linkable by free radical process, and possibly -O-CH2-CHR'- units in which R' is a substituent containing no reactive function which is cross-linkable by means of a free radical process, It is characterized by an excellent polydispersity index I=Mw/Mn and a random distribution of the different monomer units. The copolymer is prepared by an anionic copolymerization process. The copolymer is useful for preparing a solid electrolyte having good mechanical properties, a good cationic conductivity and a good chemical compatibility with the electrodes of a generator operating with alkali metals such as lithium and sodium.
