ABSTRACT:
This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the high pressure polymerization of olefins. The invention particularly relates to the use of silica gel having a particle size less than 10 microns containing from about 5 to about 20 per cent by weight absorbed water as the catalyst support material. It has been found that such silica gel may be safely added to an aluminum trialkyl solution to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane component of the catalyst system. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dried to free flowing powder. The dried free flowing powder may then be used as a catalyst for high pressure polymerization of olefins.
