Abstract

Abstract : A series of biaryl Group 4 complexes with a bidentate and a tridentate pincer ligand have been synthesized and characterized. The complexes have been applied as metallocene analogues for the controlled polymerization of ethylene and the copolymerization of ethylene and 1‐hexene, with a particular focus on the control of the degree of long chain branching in these polymers. Abstract : A series of non‐metallocene Group 4 metal complexes containing bidentate and tridentate pincer ligands with η 1 ‐aryl donors has been investigated as catalysts for polyethylene formation, with a particular focus on long chain branching as determined by rheology measurements.
