Abstract
Catalysts, suitable for olefin polymerisation e.g. polyethylene manufacture, are prepd. by reducing a transition metal cpd. e.g. TiCl4 (having normal, max. valency) with an organo-magnesium cpd. RMgOR' (where R and R' are each hydrocarbyl groups) e.g. n-butyl magnesium alkoxide, to give a transition metal cpd. (having lower valency stage) esp. TiCl3. This catalyst is activated by an organo-metallic activator e.g. aluminium trialkyl and is then suitable for olefin polymerisation.
