  • Method for the polymerization of ethylene and for the copolymerization of ethylene with alpha-olefins and catalysts for use in the method
    Patent number: 4663404
    Abstract: Method for the polymerization of ethylene and for the copolymerization of ethylene with alpha-olefins to give polymers and copolymers particularly suited to working by blow-moulding, by using a catalytic system constituted by:(a) a trialkylaluminum; and(b) a solid catalytic component obtained by the reaction of:(b1) an alkyaluminum halide, with(b2) the product of the reaction between a hafnium halide, an alcoholate of silicon, a magnesium halide, an aliphatic alcohol and a titanium alcoholate.
