NOVEL OLEFIN POLYMERIZATION CATALYSTS BASED ON IRON AND COBALT

A new family of olefin polymerization catalysts, derived from iron and cobalt complexes bearing 2,6-bis(imino)pyridyl ligands, is described.

Discovery of a new family of chromium ethylene polymerisation catalysts using high throughput screening methodology

Following a discovery that salicylaldimines bearing bulky ortho-phenoxy substituents and small imine substituents give very active chromium catalysts for ethylene polymerisation, High Throughput Screening (HTS) methodology has been employed to facilitate a further discovery of exceptionally active catalysts based on tridentate salicylaldimine ligands with bulky triptycenyl groups.
