摘要：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 aand b are each greater than 0.001 and not more than 0.50. The composition has a lowsurface area, typically less than 50 m<2>/g. The composition can be prepared by reactingtitanium tetrachloride with an organo-aluminium compound, optionally heating thereaction product, contacting the reaction product at an elevated temperature with atleast one of E and L and washing the product subsequent to the contacting with E. In thecomposition, E is conveniently di-n-butyl ether or di-iso-amyl ether and L can be anorganic phosphine, phosphine oxide, phosphite or phosphate. The composition can beused in a polymerisation catalyst to polymerise or copolymerise olefine monomers.Copolymers having an advantageous combination of low temperature brittle point andFlexural Modulus are disclosed.
