  • Catalytic system for the (co)polymerization of alpha-olefins
    Patent number: 6274529
    Abstract: A catalytic system with an increased activity for the (co)polymerization of alpha-olefins comprises a catalyst of the metallocene type, which is capable of polymerizing olefins without aluminoxane, and a weak coordinating compound, which, when used in a polymerization process, enables a higher productivity than an analogous process carried out with the metallocene type catalyst per se.
