| 摘要 |
<p>The invention relates to an olefin polymerization catalyst which is the reaction product of 1) transition metal compounds having ancillary, stabilizing ligands and at least two labile ligands suitable for insertion of olefins and capable of abstraction or removal so as to form active cationic transition metal centers and 2) a support bound Lewis acid comprising a boron atom having two halogenated aryl ligands and a third ligand being a heteroatom covalently bonded to a polymeric or metal/metalloid oxide support. Olefin polymerization with certain embodiments are illustrated. The invention includes a process for the polymerization of olefinically unsaturated monomers comprising contacting a plurality of one or more of said monomers with the invention catalyst.</p> |
