Bénédicte LEPOITTEVIN 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).

  • Polymers, methods for preparing same, and uses thereof particularly for metal capture
    Patent number: 11332566
    Abstract: Disclosed are novel polymers that contain monomer units derived from 4-vinylpyridine and monomer units derived from a co-monomer. The polymers may be complexed with a metal, and linear or crosslinked. Also disclosed are methods for preparing these polymers by radical polymerization, as well as to their use for metal capture in aqueous media, particularly uranium capture in seawater or in final nuclear waste from nuclear power plants.
    Type: Grant
    Filed: October 2, 2017
    Date of Patent: May 17, 2022
    Assignee: UNIVERSITE PARIS-SACLAY
    Inventors: Philippe Gérard Roger, Mohamad Maaz, Bilal Nsouli, Tamara Elzein, Nadine Barroca-Aubry, Bénédicte Lepoittevin
  • NOVEL GRAFT POLYMERS, METHODS FOR PREPARING SAME, AND USES THEREOF PARTICULARLY FOR METAL CAPTURE
    Publication number: 20200231722
    Abstract: Disclosed are novel polymers that are grafted onto a substrate. These polymers contain monomer units derived from 4-vinylpyridine and monomer units derived from a co-monomer. The polymers may be complexed with a metal, and linear or crosslinked. Also disclosed are methods for preparing these polymers by radical polymerisation, as well as to their use for metal capture in aqueous media, particularly uranium capture in seawater or in final nuclear waste from nuclear power plants.

  • Nanocomposite polyster preparation method
    Publication number: 20040106720
    Abstract: The invention relates to a method for preparing nanocomposite aliphatic polyester consisting of the mixing of a nanofiller in at least one monomer that can form an aliphatic polyester and the intercalative polymerisation of the mixture obtained in the presence of a supercritical fluid.
    Type: Application
