Sunita S. Satav 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).

  • Soluble polymers comprising unsaturation and process for preparation thereof
    Patent number: 7763688
    Abstract: The present invention describes the synthesis of solvent soluble copolymers containing multiple unsaturations. These copolymers contain reactive vinyl groups, which can be further reacted in a second stage polymerization. The process involves copolymerization of a vinyl monomer with an inclusion complex of a monomer having multiple unsaturations and a cyclic macromolecular compound to yield soluble polymers. These polymers may be cast into films, membranes or may be converted in micro or nanoparticles and then crosslinked in a second step polymerization.
    Type: Grant
    Filed: October 24, 2008
    Date of Patent: July 27, 2010
    Assignee: Council of Scientific and Industrial Research
    Inventors: Mohan G. Kulkarni, Rohini N. Karmalkar, Sunita S. Satav
