ABSTRACT:
The present invention provides a method of making a polymer by reacting, in the absence of water, an organic compound having the general formula R-H wherein R represents an organo radical having at least one unsaturated carbon-carbon bond and H is covalently bonded to one of said carbons, with PX.sub.3, wherein X is a halide radical, and zirconium ions to yield a reaction product and oxidizing and hydrolyzing such reaction product to yield a polymer represented by the general formula Zr(O.sub.3 PR).sub.n wherein n varies from about 1 to about 2.5. R may comprise sulfonic acid groups or may comprise sulfonatable site for sulfonation during the oxidation step. In either case, the resulting product is useful as an acid catalyst.
