摘要：A titanium trichloride composition has the formula: where E is an ether orthioether; L is an organic sulphur-containing compound; and a and b are each greaterthan 0.001 and not more than 0.50. The composition has a low surface area, typically lessthan 50 m/g. The composition can be prepared by reacting titanium tetrachloride with anorganoaluminium compound, optionally heating the reaction product, contacting thereaction product at an elevated temperature with at least E, and preferably L andwashing the product. In the composition, E is conveniently di-n-butyl ether or di-isoamylether and L can be phenoxathiin or diphenyl sulphone. The composition can be used as acomponent of a catalyst for the polymerisation of olefine monomers such as propylene.
