Abstract
A transition metal product, for example a titanium trichloride material, is obtained by milling a solid transition metal compound with a carboxylic acid or an ester thereof, for example methylmethacrylate and contacting with an organo-Lewis Base such as an amine, an organo-phosphorus compound or a sulphone derivative. The organo-Lewis Base may be milled with the transition metal compound or may be added to the transition metal compound as a solution in an inert liquid. The product can be used as a component of an olefine polymerization catalyst.
