| titleOfInvention | Process for the catalytic preparation of polymers or copolymers of alpha-olefins having a high isotacticity index, and composition based on titanium chloride suitable as component of the catalytic systems used in this process |
| abstract | A process for the catalytic preparation of polymers or copolymers of alpha-olefins having a high isotactic index by polymerization of an alpha olefin C 3 to C a, block copolymerization of such alpha-olefins with each other and / or with ethylene, or copolymerization of mixtures of such alpha-olefins with each other and / or with ethylene, the mixture containing at least 85 mole percent of one of the alpha-olefins, by means of a catalytic system of the Ziegler type -Natta formed by the association of a titanium chloride and an organic aluminum compound, and in the presence of a stereospecificity adjuvant.n n n To obtain polymers or copolymers having a high isotacticity index, the stereospecificity adjuvant is a cyclic polyether of the type of crown ethers, said polyether optionally containing sulfur atoms and / or nitrogen residues, and to give to the catalytic system excellent activity, said adjuvant can be used in combination with an activator chosen from acyclic or cyclic polyenes and dihydrocarbylacetylenes. The adjuvant or the adjuvant and the activator can be used in the process in the form of a composition obtained by premixing the latter with titanium chloride. |
