ABSTRACT:
A solid compound of a transition metal is ground in the presence of aluminium chloride, titanium tetrachloride and at least one organo-Lewis Base compound. The transition metal compound is typically titanium trichloride. The Lewis Base compound is an organo-phosphorus compound, preferably one which also contains nitrogen, such as 2-dimethylamino-1,3-dimethyl-1,3,2-diazaphospholidine-2-oxide or an organo-sulphur compound such as diphenyl sulphone. The solid compound of the transition metal may include aluminium chloride and if the amount of this aluminium chloride is at least 50% molar, there is no need to make a separate addition of aluminium chloride to the mixture which is ground. The ground product can be used as a component of an olefine polymerization catalyst.
