Abstract
A process for preparing heteroblock copolymers whose chains follow each other blocks of monomer units of one or more olefins with non-statistical distribution, with the aid of a catalyst constituted by the product of the reaction of a crystalline and solid titanium halide, in that the metal has a valence lower than the maximum, with an organometallic compound of aluminum, a process characterized in that the polymerization is carried out in the gas phase, by alternate contacting of the catalyst with the olefinic monomers to be formed, with non-statistical distribution, polymer chains.
