| titleOfInvention |
A solid titanium trichloride catalyst useful for the stereospecific polymerization of alpha-olefins and a process for its preparation |
| abstract |
The solid catalyst is pre-activated by contacting an organoaluminum pre-activator comprising the reaction product of compound (a) selected from the group consisting of organoaluminum compounds and compounds (b) selected from hydroxyaromatic compounds whose hydroxyl group is sterically blocked. This solid catalyst makes it possible to polymerize propylene with improved stereospecificity.nŕ |
