Abstract
Methods for preparing olefin polymers, and catalysts for preparing olefin polymers are disclosed. The polymers can be prepared by contacting the corresponding monomers with a Group 8-10 transition metal catalyst and a solid support. The polymers are suitable for processing in conventional extrusion processes, and can be formed into high barrier sheets or films, or low molecular weight resins for use in synthetic waxes in wax coatings or as emulsions.
