Single‐Site, Single‐Component Catalysts for Very High Molecular Weight Polyethylene: A Robust “Ready‐To‐Go” Vanadium π‐Bonded Complex Without a Preformed VC Bond

Abstract

On its own: A vanadium(II) bis(pyrrolide) complex with a vanadocene-type structure is a single-component catalyst for the preparation of ultrahigh molecular weight polyethylene (PE; see scheme; Mw=weight-average molecular weight, PDI=polydispersity index).
