Abstract
This application relates to a process for the homopolymerization (or copolymerization) of unsaturated compounds, particularly ethylene and higher alpha olefines, to give homopolymers (or copolymers) having a wide molecular weight distribution. The polymerization yields are very high, even at relatively low pressures (10 bars), i.e. such as not to require scrubbing in order to remove the catalytic residue from the polymer. These results are obtained by using, in union with an organometallic aluminium compound, a catalyst in the form of a new titanium trihalide-based chemical composition satisfying the following formula:
