Patents by Inventor Eduardo José Dotti

Eduardo José Dotti 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).

  • Extrusion coating resin from tubular reactor
    Patent number: 11396562
    Abstract: A method may include polymerizing ethylene in a tubular reactor, where the polymerization is substantially free of a chain transfer agent. A method may include polymerizing ethylene in a tubular reactor, the ethylene having a specific delivery pressure and the polymerization having one or more specific peak temperatures. The molecular weight of the resulting polyethylene may be controlled by the selection of the delivery pressure and the one or more peak temperatures.
    Type: Grant
    Filed: March 16, 2020
    Date of Patent: July 26, 2022
    Assignee: Braskem S.A.
    Inventors: Eduardo José Dotti, Omar Wandir Renck, Roger Ribeiro Malmegrim, Marcelo Farah, Antonio Marchi Netto, Cid Miro Neto, Jorge Manuel Jardim da Silva
  • Tubular reactor polymerization initiator injector device, tubular reactor for continuous polymerization of olefins, and a process for production of polymers and copolymers of ethylene
    Patent number: 10829568
    Abstract: The present invention refers, in its generality, to a tubular reactor for homo or copolymerization of olefins, with one of more initiator injection devices. The invention also refers to an initiator device in a process fluid stream in a reactor polymerization reactor, and to a process for the production of polymers and copolymers of ethylene, particularly low density polymers (LDPE), that use the said device.
