Abstract
A titanium trihalide component of an olefine polymerization catalyst is prepared by reacting together a titanium tetrahalide and an organo-aluminium compound, and treating the solid reaction product with a hydrocarbon solution of an alkyl aluminium dihalide. It is preferred that the solid reaction product is treated with a complexing agent, particularly an ether such as di-isoamyl ether before contacting with the alkyl aluminium dihalide. The titanium trihalide can then be used together with an organo-metallic compound to polymerize an olefine monomer, particularly propylene. The catalyst system may include further components in addition to the titanium trihalide and organo-metallic compound.
