Abstract
The instant invention provides a polymerization process for producing ethylene based polymers. In one embodiment, the instant invention provides a polymerization process for producing ethylene based polymers comprising: polymerizing ethylene with optionally one or more α-olefins in the presence of one or more first catalyst systems and optionally one or more second catalyst systems in a single reactor, wherein first catalyst system comprises; (a) one ore more procatalysts comprising a metal-ligand complex of formula (I):
Claims1
A polymerization process for producing ethylene based polymers comprising:
- polymerizing ethylene and optionally one or more α-olefins in the presence of one or more first catalyst systems and optionally one or more second catalyst systems in a single reactor, wherein first catalyst system comprises;
- (a) one or more procatalysts comprising a metal-ligand complex selected from the group consisting of
- and
- (b) one or more cocatalysts;
- wherein the ratio of total number of moles of the one or more metal-ligand complexes of formula (I) to total number of moles of the one or more cocatalysts is from 1:10,000 to 100:1.
