  • Olefins produced from pre-polymerized catalyst component catalysts
    Patent number: 6797794
    Abstract: Olefin polymers produced using components of catalysts obtained by contacting a Ti compound of formula Ti(OR)n-yXy, where n is the valence of titanium and y is a number between 1 and n, with a pre-polymer having a porosity higher than 0.3 cc/g and containing from 0.5 to 100 g of polymer per g of solid catalyst component, the pre-polymer being obtained by (co)polymerizing an olefin or a diolefin in the presence of a catalyst comprising a Ti, V, Zr or Hf compound supported on a Mg dihalide having a mean crystallite dimension lower than 30 nm.
    Type: Grant
    Filed: July 24, 2002
    Date of Patent: September 28, 2004
    Assignee: Basell Poliolefine Italia S.p.A.
    Inventors: Licio Zambon, Mario Sacchetti, Gianni Vitale
