Polymer Syntheses and Mechanisms of Polymerization
Abstract
The major outcome of the research was the discovery that acetylenes induce metal-derivatives to initiate methatheses of olefins. This discovery provides a simple way to synthesize a variety of polymers from cyclic olefins. Research to demonstrate the mechanism by which acetylenes induce methatheses showed that polyacetylenes appear as a block at the start of polyalkenamer chains. The initiation of the olefin methathesis quenches the acetylene polymerization. The size of the block revealed for the first time how the reactivities toward metal-carbenes differ for acetylenes and alkenes.
