ABSTRACT:
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).
