Hervé Adam 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).

  • Patent number: 10836856
    Abstract: Paint, clear coat, stain, adhesive, or other aqueous formulations that contain at least one [(dimethylamino)alkyl]-imino-dialcohol and a alkyd emulsion, polymer latex or polyurethane dispersion binder. Also disclosed are methods for manufacture and use of these formulations. The [(dimethylamino)alkyl]-imino-dialcohols provide aqueous formulations having low odor and reduced volatile organic compounds (VOC). The [(dimethylamino)alkyl]-imino-dialcohols also aid in dispersing pigment and other solids so less co-dispersant is needed for aqueous paint or coating formulations.
    Type: Grant
    Filed: May 20, 2015
    Date of Patent: November 17, 2020
    Assignee: RHODIA OPERATIONS

  • Patent number: 9422671
    Abstract: The present invention relates to a process of making aqueous dispersions of copolymers, for example based on conjugated, aliphatic dienes and vinyl aromatic compounds. It relates also to the emulsions polymers obtained thereby, and to the use thereof as binders for the coating of paper. The invention also related to a coated paper having a coating comprising the emulsion copolymer. The process involves using at least two emulsifiers.

  • Publication number: 20160113856
    Abstract: Disclosed is a pH responsive polymer made with mono-[2-(methacryloyloxy)ethyl]phthalate and/or mono-[2-(methacryloyloxy)ethyl hexahydro]phthalate. Also disclosed is an aqueous coating composition including at least one latex polymer derived from at least one monomer copolymerized or blended with alkali swellable acrylate copolymer. Also provided is an aqueous coating composition including at least one latex polymer derived from at least one monomer blended with alkali swellable acrylate copolymer, at least one pigment, and water. Also provided is a method of preparing an aqueous coating composition such as a latex paint including the above components. Also provided are methods of preparing mono-[2-(methacryloyloxy)ethyl]phthalate. Also provided are compositions and methods using the polymer in hydraulic fracturing, personal care and or home and industrial cleaners.

  • Patent number: 9115236
    Abstract: The invention relates to a copolymer having: A) at least one monomer unit a) derived from at least one ethylenically unsaturated aliphatic monocarboxylic or polycarboxylic acid, a corresponding anhydride, or a corresponding water-soluble salt; B) at least one monomer unit b) derived from a particular sulfonated or sulfated ethylenically unsaturated ether or at least one monomer unit (b?) derived from a sulfonated ethylenically unsaturated monomer other than (b), C) at least one monomer unit (c) derived from a monomer with the average general formula [CH2?CH—CH2—R6—O—]xP(?O)(OM)3-x. The invention also relates to a method for preparing such a copolymer, an inhibitor composition including such a copolymer, and a method for inhibiting inorganic deposits in a petroleum reservoir by means of said inhibitor composition.
