CATALYST FOR POLYMERIZING OLEFINS Abstract of the Disclosure A novel catalytic system for polymerizing olefins comprises: a) a cocatalytic component containing an organo- metallic compound of Groups I-III of the periodic table, and b) a catalytic component containing titanium obtained by: (i) copulverizing a substantially anhydrous magnesium compound containing halogen or man- ganese compound containing halogen with: a phenol, an organic polymer containing silicon, a titanium halide, and an electron-donor com- pound to produce a copulverized product, and (ii) reacting the copulverized product with a liquid titanium compound containing halogen. The invention also encompasses the novel catalytic component, processes for preparing the catalytic com- ponent containing titanium, and the use of the novel catalytic system for polymerizing olefins. * * * * * *
