Claims20
A solid pre-catalyst component comprising titanium, magnesium, a halogen, and a boron-based internal electron donor.
A solid pre-catalyst component for use in olefinic polymerization, comprising a reaction product of a titanium compound, a magnesium compound, and a boron-based internal electron donor.
A process of polymerizing or co-polymerizing an olefin monomer, the process comprising:
- providing a catalyst system comprising:
- a solid pre-catalyst component comprising titanium, magnesium, a halogen, and a boron-based internal electron donor;
- and
- an organoaluminum compound;
- polymerizing or co-polymerizing the olefin monomer in the presence of the catalyst system to form a polymer or a co-polymer;
- and
- recovering the polymer or the co-polymer.
