NICKEL DIIMINE CATALYSTS WITH METHYLALUMOXANE AS COCATALYST, METHOD OF POLYMERIZATION OF OLEFINS THEREWITH AND POLYMERS PRODUCED.

摘要

Novel catalyst systems which comprise diimine nickel complexes comprising additional ligands selected from the group consisting of acetylacetonate, hexaflourylacetylacetonate, halogens and mixtures thereof can be used with methylaluminoxane in slurry polymerization processes to polymerize mono-1-olefins and, optionally one or more higher mono-1-olefin comonomer(s), to produce high molecular weight polymers.
