  • Method for producing aqueous polymer dispersions
    Patent number: 9090749
    Abstract: Process time for finishing aqueous polymer dispersions is significantly reduced by cooling the aqueous polymer dispersion from the polymerization by a heat exchanger prior to entry into a storage vessel. The dispersion may enter a letdown vessel prior to being cooled. Finishing additives are metered into the dispersion following cooling but prior to entry into the storage vessel.
    Type: Grant

  • Stereorigid metallocene compounds
    Patent number: 6410661
    Abstract: A stereorigid metallocene compound contains, as ligands, an aryl-substituted cyclopentadienyl radical, linked via a hydrogen bridge, and a substituted or unsubstituted fluorenyl radical. The novel metallocene compound is suitable as a catalyst component for olefin polymerization.
