Patents by Inventor Mathieu Chirat

Mathieu Chirat 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).

  • Polycarboxylic acid polymers
    Patent number: 8227560
    Abstract: The present invention relates to methods and polymers based upon vinyl type monomers that contain pendant carboxylic acid groups and ester group functionality. The polymers may be prepared under selected conditions of partial neutralization to provide relatively high conversions and/or relatively high values of molecular weight and/or selected amounts of repeating unit tacticity.
    Type: Grant
    Filed: March 8, 2011
    Date of Patent: July 24, 2012
    Assignee: University of New Hampshire
    Inventors: Yvon Durant, Ming Cao, Mathieu Chirat

  • Absorbing materials containing polycarboxylic acid polymers
    Patent number: 7915365
    Abstract: The present invention relates to methods of forming absorbent materials and polymers used in absorbent materials, which are based upon vinyl type monomers that contain pendant carboxylic acid groups and ester group functionality. The polymers may be prepared under selected conditions of partial neutralization to provide relatively high conversions and/or relatively high values of molecular weight and/or selected amounts of repeating unit tacticity. The polymers may then be used in absorbing materials.
