  • Articles comprising broad molecular weight distribution polypropylene resins
    Patent number: 9902822
    Abstract: Disclosed herein are embodiments of films which comprise a polypropylene resin comprising at least 50 mol % propylene, an MWD (Mw/Mn) of greater than 5, a branching index (g?) of at least 0.95, and a melt strength of at least 20 cN determined using an extensional rheometer at 190° C. A method of making a film is also disclosed.
    Type: Grant
    Filed: October 8, 2013
    Date of Patent: February 27, 2018
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Saifudin M. Abubakar, Prasadarao Meka, Stefan B. Ohlsson
  • Spunbond Fabrics Comprising Propylene-Based Elastomer Compositions and Methods for Making the Same
    Publication number: 20170314171
    Abstract: A polymer composition for forming spunbond fabrics offers a unique combination of simplicity and processability, while allowing fabrics formed therefrom to exhibit suitable elasticity and/or tensile strength. The polymer composition includes an propylene-based elastomer component exhibiting a particular combination of MFR and comonomer content, so as to allow for improved processability with minimal, if any, need for blending partners in the polymer composition, while still permitting fabrics formed therefrom to exhibit improved elasticity and/or tensile strength.

  • Broad molecular weight distribution polypropylene resins
    Patent number: 9453093
    Abstract: Polypropylene resin comprising at least 50 mol % propylene, an MWD (Mw/Mn) of greater than 5, a branching index (g?) of at least 0.95, and a melt strength of at least 20 cN determined using an extensional rheometer at 190° C. A catalyst system comprising a Ziegler-Natta catalyst comprising a non-aromatic internal electron donor, and first and second external electron donors comprising different organosilicon compounds, and a method to produce a polypropylene resin comprising contacting propylene monomers at propylene polymerization conditions with the catalyst system are also disclosed.
