Titanium trichloride compositions, preparation thereof, catalyst system containing them, and polymerisation of olefins using this system. |
摘要 |
A titanium trichloride composition has the formula:
TiCl3(AlRxX3-x)nEaLb
where E is an ether or thioether; L is a defined ester, an amine or a ketone; and a and b are each greater than 0.001 and not more than 0.50. The composition has a low surface area, typically less than 50 m<2>/g. The composition can be prepared by reacting titanium tetrachloride with an organo-aluminium compound, optionally heating the reaction product, contacting the reaction product at an elevated temperature with at least one of E and L and washing the product 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. The composition can be used as a component of a catalyst for the polymerisation of olefine monomers such as propylene. Copolymers having a useful combination of properties can be obtained.
