Abstract
Abstract A catalytic system for polymerizing olefins comprises: (a) a component containing an organoaluminum compound, and (b) a component containiong a titanium halide prepared by a process comprising: (i) intimately contacting a magnesium compound containing halogen or a manganese compound containing halogen with a carboxylic acid to produce an activated product, (ii) optionally treating the activated product with a phenol, and (iii) reacting the activated product, optionally treated with phenol, with a titanium halide compound. The invention also includes a process for preparing component (b) containing a titanium halide, the composition of component (b), and the use of the catalytic system for polymerizing olefins such as ethylene or propylene.
