  • Homogeneous process for the ruthenium catalyzed addition of carboxylic acids to alkynes
    Patent number: 5430179
    Abstract: The present invention relates to a homogeneous, ruthenium catalyzed liquid phase process for vinyl ester synthesis. It has been found that by adding at least one selectivity enhancer to the reaction system, selectivity to the addition reaction is improved while byproduct formation is inhibited. Useful selectivity enhancers include non-reacting heteroatom containing molecules that are believed to act by weakly coordinating to the ruthenium/phosphine ligand complex.

  • Process utilizing alkenylcarboxylate crosslinkers
    Patent number: 5412038
    Abstract: A process for crosslinking a polymer containing hydroxyl groups which process comprises:(a) forming a mixture of said polymer and crosslinking amount of a poly(alpha, beta-alkenylcarboxylate), and(b) maintaining the mixture at conditions under which the polymer cures by reaction of the hydroxyl groups of the polymer with the poly(alpha, beta-alkenylcarboxylate) to produce a crosslinked polymer.
