Half-titanocene pre-catalysts for olefin polymerisation

This article is HOT as recommended by the referees.

The complexes helped produce polymers with narrow polydispersity and high molecular weights.

The complexes helped produce polymers with narrow polydispersity and high molecular weights.

Synthetic polymers are everywhere in modern life and offer multiple opportunities for future materials with a wide range of applications.  Using transition metal complex catalysts to precisely control olefin polymerisation is of current interest as they allow the synthesis of polyolefins with set microstructures.  Carl Redshaw, Wen-Hua Sun and colleagues have synthesised and fully characterised a series of half-titanocene dichloride 2-aryliminoquinolin-8-olates and tested them with modified methylaluminoxane co-catalysts in ethylene polymerisations and co-polymerisations.
