  • Process for the polymerization of olefins
    Patent number: 7138469
    Abstract: Process for the polymerization of olefins CH2?CHR, in which R is hydrogen or a hydrocarbon radical with 1–12 carbon atoms, carried out in the presence of a catalyst component (A) comprising Mg, Ti and halogen as essential elements and of a catalyst component (B) capable to produce, under the same polymerization conditions, a polymer with an average particle size lower than that obtainable with the said catalyst component A. The said process provides polymers with increased bulk density.
    Type: Grant
    Filed: December 10, 2002
    Date of Patent: November 21, 2006
    Assignee: Basell Poliolefine Italia S.p.A.
    Inventors: Gianni Collina, Ofelia Fusco, Eduardo Chicote Carrion, Alberto Gil, Volker Dolle, Horst Klassen, Karl-Heinz Kagerbauer
  • Process for the polymerization of olefins
    Publication number: 20040077490
    Abstract: Process for the polymerization of olefins CH=CHR, in which R is hydrogen or a hydrocarbon radical with 1-12 carbon atoms, carried out in the presence of a catalyst component (A) comprising Mg, Ti and halogen as essential elements and of a catalyst component (B) capable to produce, under the same polymerization conditions, a polymer with an average particle size lower than that obtainable with the said catalyst component A. The said process provides polymers with increased bulk density.

  • Peroxidic treatment of olefin polymers
    Patent number: 6313228
    Abstract: A process peroxidically treats olefin polymers with di-tert-butyl peroxide in an extruder. The olefin polymers together with di-tert-butyl peroxide under an inert gas are fed to an extruder. The olefin polymers are used in a finely divided form at from 55 to 110° C. The use of peroxidically treated olefin polymers for producing moldings, fibers, films or nonwoven spunbond fabrics is described, as is a process for producing moldings, fibers, films or nonwoven spunbond fabrics.
