Abstract
A catalytic system for polymerizing olefins contains an organoaluminum compound and a component containing titanium halide on a support of a magnesium or manganese compound containing halogen, which is obtained by (i) pretreating the support with an ether, (ii) intimately contacting the support with an electron donor, to activate it, and (iii) reacting the activated support with a titanium halide, such as titanium tetrachloride. The invention also includes the process for preparing the titanium component, the composition of the titanium component, and the use of the novel catalytic system to polymerize olefins.
