    摘要: Process for the polymerization of selected vinyl ethers catalyzed by yttrium or rare earth metal perfluoroalkylsulfonates. A preferred perfluoroalkylsulfonate anion is triflate (trifluoromethanesulfonate). The resulting polymers are useful as tackifiers in adhesives as well as in other uses (e.g., plasticizers, viscosity modifiers).

    摘要: Fluorinated ion exchange polymers which have pendant side chains which contain ##STR1## groups wherein W is F or CF.sub.3, and R is an ionizable group, or which have such pendant side chains and also pendant side chains which contain sulfonyl groups, when used in the form of membranes to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency. They can be made by copolymerization of a mixture of monomers, one of which is a vinyl monomer which contains the indicated carboxylic functional group.
