  • Process for preparing 1-olefin (co) polymers
    Patent number: 7759445
    Abstract: For the (co) polymerization of ethylene with other 1-olefins, a Ziegler catalyst which comprises the product from the reaction of a magnesium alkoxide suspended or dispersed as ge in an inert solvent with a tetravalent transition metal compound and is subjected to a thermal after-treatment for a period of not more than 180 minutes is prepared. The catalyst gives a high yield of a polymer powder which has a broad molar mass distribution and is best suited to the production of films, hollow bodies and pipes.
    Type: Grant
    Filed: February 15, 2006
    Date of Patent: July 20, 2010
    Assignee: Basell Polyolefine GmbH
    Inventors: Friedhelm Gundert, Maria Schmitt (nee Fusto), Martin Schneider
