Abstract
The present disclosure provides a process. In an embodiment, the process includes providing a purge stream containing octene monomer. The process includes contacting, under polymerization conditions, the purge stream with a bis-biphenylphenoxy catalyst, and forming an octene polymer having an absolute weight average molecular weight (Mw(Abs)) greater than 1,300,000 g/mol and a Mw(Abs)/Mn(Abs) from 1.3 to 3.0.
Claims6
A process comprising:
- providing a purge stream comprising octene monomer;
- contacting, under polymerization conditions, the purge stream with a bis-biphenylphenoxy catalyst having a formula (V)
- or having the formula (VI)
- and
- forming an octene homopolymer having an absolute weight average molecular weight (Mw(Abs)) greater than 1,300,000 g/mol and a Mw(Abs)/Mn(Abs) from 1.3 to 3.0, the octene homopolymer comprising a residual amount of zirconium in an amount from greater than 0 ppm to less than 300 ppm.
