  • Process for extruding polypropylene
    Patent number: 10954360
    Abstract: A process for extruding polypropylene comprising extruding a composition comprising a polypropylene and a second acid scavenger and less than about 10 ppm of a nucleating agent.
    Type: Grant
    Filed: May 24, 2018
    Date of Patent: March 23, 2021
    Assignee: Milliken & Company
    Inventors: Kemper D. Lake, Jr., Christopher T. Kochanowicz, Joseph J. Peterson, Clifford S. Bynum, Keith A. Keller
  • METHOD FOR MAKING HETEROPHASIC POLYMER COMPOSITIONS
    Publication number: 20200270435
    Abstract: A heterophasic polymer composition comprises a propylene polymer phase, an ethylene polymer phase, a compatibilizing agent comprising a fulvene moiety, and a nucleating agent. A method for modifying a heterophasic polymer composition comprises the steps of providing a compatibilizing agent, providing a nucleating agent, providing a heterophasic polymer composition comprising a propylene polymer phase and an ethylene polymer phase, mixing the compatibilizing agent, the nucleating agent, and the heterophasic polymer composition, and generating free radicals in the propylene phase and the ethylene phase. At least a portion of the compatibilizing agent then reacts with free radicals in both the propylene polymer phase and the ethylene polymer phase to form a bond with a propylene polymer in the propylene polymer phase and a bond with an ethylene polymer in the ethylene polymer phase.
