A B S T R A C T Titanium trichloride for use as a component of a Ziegler polymerisation catalyst is modified in order to enhance the activity and/or stereospecificity of the catalyst in the polymerisation of olefins, especially propylene, by heating the titanium trichloride with phosphorus oxytrichloride in an aromatic hydrocarbon diluent for several hours in the absence of the organo aluminum component of the catalyst. Ball milling, or shearing, during the modification reaction is not required. The use of aromatic hydrocarbon give unexpected improvement compared with any other hydrocarbon diluent and the modification reaction give improved results compare with addition of the titanium trichloride, phosphorus oxytrichloride and the organo aluminum component to the reactor at the beginning of a batch polymerisation.
