Productivity catalysts and microstructure control

Improved Group 3-11 transition metal based catalysts and processes for the polymerization of olefins are described. Some of the ligands are characterized by a preferred substitution pattern which allows for higher productivities of highly branched olefins; substitution patterns which boost productiv...

More Information
Summary:Improved Group 3-11 transition metal based catalysts and processes for the polymerization of olefins are described. Some of the ligands are characterized by a preferred substitution pattern which allows for higher productivities of highly branched olefins; substitution patterns which boost productivity or alter the polymer microstructure are also described.
