| titleOfInvention | Transition metal composition |
| abstract | A titanium-containing composition is obtained by forming a magnesium halide-ester material, suspending this material in a liquid medium containing titanium tetrachloride, (preferably undiluted liquid titanium tetrachloride at elevated temperature) separating the solid from the liquid phase, repeating the treatment with titanium tetrachloride, and washing the solid product at least once to give a product in which the titanium level is in the range from 1 up to 5% by weight. The magnesium halide-ester material is conveniently produced by grinding together magnesium halide and an ester, such as magnesium chloride and ethyl benzoate. The titanium-containing composition may be combined with an organic metal compound such as aluminium triethyl and preferably a Lewis Base, particularly an ester such as ethyl benzoate, methyl p-methylbenzoate, or ethyl p-methoxy-benzoate, to give olefin polymerisation catalyst. The particle form of the titanium-containing composition can be improved by including a spray-drying step in the process of producing the composition or by spray- drying the composition when it has been produced. |
