Matthew John FEDEC 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).

  • Propylene-ethylene random copolymers with low XS/ET ratio and high MFR
    Patent number: 11905347
    Abstract: Propylene and alpha olefin random copolymers are disclosed that have excellent flow characteristics. For instance, the copolymers can be formulated so as to have a melt flow rate of greater than about 45 g/10 min. While still retaining the above flow characteristics, the copolymer can also be formulated to have greater stiffness, low xylene soluble content, and excellent transparency characteristics especially when combined with one or more clarifying agents.
    Type: Grant
    Filed: June 7, 2019
    Date of Patent: February 20, 2024
    Assignee: W.R. GRACE & CO .- CONN.
    Inventors: Matthew John Fedec, Jan Willem Van Egmond, John Kalevi Kaarto, Amaia Montoya-Goni
  • Propylene-ethylene copolymer compositions suitable for hot fill packaging of foodstuffs
    Patent number: 11873355
    Abstract: Propylene-ethylene copolymer compositions and production methods are provided. The copolymer compositions can be particularly advantageous for use in hot fill packaging of foodstuffs. The propylene-ethylene copolymers can be produced using a Ziegler-Natta catalyst and an alkoxysilane electron donor. The compositions can have propylene as a primary monomer with an ethylene content ranging from 2.0 to 6.0 percent by weight with a xylene soluble content of less than 7.0 percent by weight.
