Patents by Inventor Henri Sautereau

Henri Sautereau 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).

  • Use of polymer compositions for coating surfaces, and surface coatings comprising such compositions
    Patent number: 6612343
    Abstract: The invention describes the use of compositions containing at least one thermoplastic polymer and an epoxy resin modified by at least one aromatic polyamine to coat surfaces, especially pipes through which oil is transported. The polymer compositions used contain at least one thermoplastic polymer which is preferably amorphous selected from the group formed by polysulphones, polyetherimides and polyphenylene esters and at least one epoxy resin modified by at least one aromatic polyamine containing at least two primary amine groups in its molecule. Different layers of polymers are deposited on different types of surface, more particularly as internal and external coatings for conduits. The invention also provides a surface coating comprising such compositions. Multi-layer coatings are also produced.

  • Alveolar materials that contain at least one thermoplastic polymer, at least one modified epoxide resin and at least one pore-forming agent
    Patent number: 6403669
    Abstract: Alveolar materials that comprise at least one thermoplastic polymer that is selected from the group that is formed by polyetherimides, polysulfones and polyphenylene-ethers, at least one epoxide resin that is modified by at least one aromatic polyamine and at least one pore-forming agent or the degradation product(s) of said pore-forming agent, their syntheses and their uses.
