Abstract
Disclosed herein are methods for producing a polymer. One polymerizes monomers selected from alkene monomers and terminal alkyne monomers, in the presence of a catalyst which is a silylene. The catalyst can be a heterocyclic amido silylene which is at least partially unsaturated within the ring. Also disclosed are polymers produced by the above methods, and improved methods for producing the catalysts.
