Abstract
This invention provides catalyst compositions that are useful for polymerizing at least one monomer to produce a polymer. This invention also provides catalyst compositions that are useful for polymerizing at least one monomer to produce a polymer, wherein said catalyst composition comprises contacting a organometal compound/organoaluminum mixture, a treated solid oxide compound, and, optionally, a second organoaluminum compound. The solid oxide has been treated with an electron-withdrawing compound, in particular a chlorine, preferably zinc chloride and carbon tetrachloride.
