Claims10
A terminally unsaturated olefin of the formula
- wherein R is oxygen or an alkylene or alkylene ether group wherein one or more of the hydrogens may be substituted by halogen, and Rf is a radical of the formula
- wherein Rf′ is a bond or is a fluoroalkylene or fluoroalkylene ether group, Y is F or O, Z is a univalent metal and m=0 or 1 with the proviso that m=0 when Y is F, and m=1 when Y is O, Rf being ionizable in character when m=1.
