  • High melt strength polypropylene
    Patent number: 7365136
    Abstract: The present invention concerns a high melt strength propylene polymer or copolymer suitable for manufacturing foams and thermoformed product exhibiting a melt strength of at least 3 g and comprising a high molar mass portion and a low or medium molar mass portion. The polymers are produced by subjecting propylene and optionally other olefins to polymerization in a plurality of polymerization reactors connected in series, employing different amounts of hydrogen as a molar mass modifier in at least two of the reactors, and carrying out the polymerization reaction in the presence of a catalyst system capable of catalyzing the formation of a high molar mass polymerization product having a MFR2 of less than 0.1 g/10 min and a low or medium molar mass polymerization product having a MFR2 of more than 0.5 g/10 min.
    Type: Grant
    Filed: March 8, 2005
    Date of Patent: April 29, 2008
    Assignee: Borealis Technology Oy
    Inventors: Paivi Huovinen, Ali Harlin, Pirjo Jaaskelainen, Amir Karbasi, Nina Manner
