摘要：A titanium trichloride composition has the formula: where E is an ether orthioether; L is a defined ester, an amine or a ketone; and a and b are each greater than0.001 and not more than 0.50. The composition has a low surface area, typically less than50 m/g. The composition can be prepared by reacting titanium tetrachloride with anorgano-aluminium compound, optionally heating the reaction product, contacting thereaction product at an elevated temperature with at least one of E and L and washing theproduct subsequent to the treatment with E. In the composition, E is conveniently di-n-butyl ether or diisoamyl ether and L can be tetramethylethylenediamine; ethyl benzoate;benzophenone; glycerol monostearate; glycerol triacetate; glycerol tripalmitate;glycerol trimethacrylate; pentaerythritol tetra-acrylate or ethyl phenyl acetate. Thecomposition can be used as a component of a catalyst for the polymerisation of olefinemonomers such as propylene. Copolymers having a useful combination of properties canbe obtained.
