Mark D. Barbieri has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Recirculation loop reactor bulk polymerization process
    Patent number: 7906598
    Abstract: A process for producing polymer and more particularly adhesive using a recirculating loop reactor. In one embodiment the reactor includes one or more mixers to mix feed stock with the polymerized material recirculating in the reactor. In another embodiment a planetary roller extruder (PRE) may be used for this purpose. In still another embodiment, a combination of one or more static mixers and one or more PREs may be used.
    Type: Grant
    Filed: September 30, 2008
    Date of Patent: March 15, 2011
    Assignee: Intertape Polymer Corp.
    Inventors: Mark D. Barbieri, Richard W. St. Coeur, John K. Tynan, Jr., Mark A. Lewandowski

  • PLUG FLOW BULK POLYMERIZATION OF VINYL MONOMERS
    Publication number: 20100105847
    Abstract: A process for continuous bulk polymerization is disclosed that includes providing a plug flow reactor comprising a primary loop reactor including a loop for recirculating a portion of a polymer-in-progress at a polymer flow rate back to a reactor in the primary loop reactor, introducing at least one monomer into the primary recirculation loop reactor at a monomer flow rate, polymerizing the monomer in the primary recirculation loop reactor in the presence of an initiator by way of a free-radical polymerization to form a polymer-in-progress, and recirculating a first portion of the polymer-in-progress through the loop into a reactor in the primary loop reactor to combine with the monomer at a ratio of polymer flow rate to monomer flow rate that is greater than 5.
