MULTIPLE CATALYST SYSTEM COMPRISING METALLOCENES AND TRIDENTATE NITROGEN BASED LIGAND COMPLEXES FOR OLEFIN POLYMERISATION

摘要

Catalyst systems and methods for making and using the same are described herein. A catalyst system can include at least three catalysts. The three catalysts include a metallocene catalyst, a first non-metallocene including a ligand complexed to a metal through two or more nitrogen atoms, and a second non-metallocene including a ligand complexed to a metal through one or more nitrogen atoms and an oxygen atom.

1. A polymerization catalyst system, comprising at least three catalysts, comprising:
a metallocene catalyst; a first non-metallocene comprising a ligand complexed to a metal through two or more nitrogen atoms; and a second non-metallocene comprising a catalyst of the formula:or any combinations,wherein X1 and X2 are each, independently, phenyl, methyl, chloro, fluoro, or a hydrocarbyl group.
