Abstract
This invention is generally directed toward a supported catalyst system useful for polymerizing olefins. The invention particularly relates to a supported metallocene catalyst system that does not require an activator or cocatalyst for the polymerization of olefins.
Claims
1. A supported metallocene catalyst system comprising a) a carrier; b) a metallocene compound; and c) an amount of organometallic compound wherein the mole ratio of the metal of the organometallic compound to the metal of the metallocene compound is less than 0.9 to 1.
2. The catalyst system of claim 1 wherein the mole ratio is less than 0.4 to 1.
3. The catalyst system of claims 1 or 2 wherein the organometallic compound comprises an alkylalumoxane, preferably methylalumoxane.
4. The catalyst system of any preceding claim wherein the carrier comprises silica.
5. A process for polymerizing and/or prepolymerizing one or more olefins, said process comprising polymerizing in the presence of the supported catalyst system of any one of the preceding claims.
