Abstract (en)
A titanium trichloride composition has the formula: TiCl3(AlRxX3-x)nEaLb where E is an ether or thioether; L is an organic phosphorus-containing Lewis Base; 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 contacting with E. In the composition, E is conveniently di-n-butyl ether or di-iso-amyl ether and L can be an organic phosphine, phosphine oxide, phosphite or phosphate. The composition can be used in a polymerisation catalyst to polymerise or copolymerise olefine monomers. Copolymers having an advantageous combination of low temperature brittle point and Flexural Modulus are disclosed.
