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.
