Patent ID: 7196148

Claim:
An olefin polymerization process comprising: (a) providing monomer; (b) providing a polymerization catalyst comprising: (i) a Group -7, -8 or -9 metal in a +3 oxidation state; (ii) a multidentate ligand comprising: (iii) a subpart comprising at least three Group-15 moieties, each bridged to another through at least one Group-14 moiety wherein the subpart connects to the metal and wherein each Group-15 moiety is optionally bonded to a substituted or unsubstituted organic group; (iv) a monoanion connected to the metal, wherein the monoanion is other than cyclopentadienyl; and (v) a bridge that connects the monoanion to the subpart; (c) contacting the monomer with the catalyst under suitable polymerization conditions.
