CATALYST FOR OLEFIN POLYMERIZATION

摘要

A supported catalyst for olefin polymerization comprises a combination of a sulfated metal oxide support, an aluminoxane and an organometallic complex of a group 4 metal. The sulfated metal oxide may be quickly and conveniently prepared by, for example, contacting the precursor metal oxide with a sulfuric acid. The supported catalyst of this invention is highly active for olefin polymerization in comparison to conventional catalysts which are prepared with non-sulfated supports.
