Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.

Copolymers of vinyl- and allylsilanes

Atomic layer deposition processes for the formation of tantalum-containing films on surfaces are provided. Also provided are novel tantalum complexes that can be used as tantalum precursors in the disclosed deposition processes.

Copolymers of olefins and vinyl- and allylsilanes

Polymers are produced using transition metal complexes that have sites capable of binding a Lewis acid in close proximity to the metal center.
