Vinyl terminated polyolefins with long chain branching produced with Salan catalysts having carbazole moieties.
First claim
Opening claim text (preview).
What is claimed is: 1. A process comprising: contacting one or more olefins with a catalyst system at a temperature, a pressure, and for a period of time sufficient to produce a polyolefin comprising a) at least 50% allyl chain ends; and b) an Mn of at least 200 g/mol, as determined by 1 H NMR; the catalyst system comprising an activator and a catalyst compound according to Formula I, Formula II, or a combination thereof: Formula I being represented by:…
