摘要: A supported catalyst for olefin polymerization comprises a combination of a novel metal oxide support and an activator which is an aluminoxane or a boron activator. The novel metal oxide support of this invention is a conventional particulate metal oxide support material (such as silica or alumina) which has been treated with a halosulfonic acid. A catalyst system which contains this novel catalyst support and a transition metal catalyst is highly active for olefin polymerization (in comparison to prior art catalyst systems which use a conventional metal oxide support).

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.

摘要: A catalyst system comprises 1) a group 4 organometallic catalyst and 2) an activator comprising a solid zirconium acid component and a metal alkyl. The catalyst system is inexpensive and is highly active for the polymerization of olefins. Preferred organometallic catalysts contain a cyclopentadienyl ligand, a phosphinimine ligand and or a ketimide ligand.
