The present invention relates to terminal unsaturated olefins of the general formula (III).n n n <Formula III>n n n n n n n n Wherein R is oxygen or an alkylene or alkylene ether group in which one or more hydrogens may be substituted by halogen, and R f is a radical of formula II.n n n <Formula II>n n n n n n n n Wherein R f ′ is a bond or a fluoroalkylene or fluoroalkylene ether group, Y is F when m is 0, Y is O when m is 1, and Z is a monovalent metal . The present invention also relates to the polymerization of the olefins and the polymers produced, as well as to the use in ionic conductive compositions, in particular electrochemical cells, wherein m is 1 and Z is hydrogen or an alkali metal. |
