Abstract: The present disclosure provides a method for preparing a catalyst system comprising contacting in an aliphatic solvent at a temperature of from less than 0° C. to −60° C. at least one support material having absorbed water and at least one hydrocarbyl aluminum compound to form a supported alumoxane (catalyst precursor) and contacting the supported alumoxane with at least one catalyst compound having a Group 3 through Group 12 metal atom or lanthanide metal atom. The supported alumoxane may be heated prior to contact with the catalyst compound.

Abstract: Disclosed are methods for the production of polymers, including random copolymers (RCPs), in single reactor gas or slurry phase polymerization processes, and polymer compositions produced therefrom. The methods enable polymers having low melting temperatures to be made in gas and slurry phase polymerization processes, where they conventionally could not be made in these processes due to stickiness and fouling problems in the reactor.
