Dillip Mohanty 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).

  • Publication number: 20060264597
    Abstract: We report Michael addition products between primary amines and activated ?,?-unsaturated compounds exemplified by diethyl methylenemalonate (DEMM). In various embodiments, the reaction proceeds with high yields in the absence of strong base or Lewis acid catalyst under mild reaction conditions. Depending on the state of steric hindrance in the amine, the reaction products are a double Michael addition product or a so-called vicarious Michael addition reaction product.

  • Publication number: 20060264530
    Abstract: Dendrimeric compounds and polymers are also provided wherein the dendrimer core is derived from the Michael reaction products. The branching pattern of the core and the multiplicity of the Michael addition lead to flexibility in designing and synthesizing dendrimeric materials. The Michael addition products are from a reaction between primary amines and activated ?,?-unsaturated compounds exemplified by diethyl methylenemalonate (DEMM). In various embodiments, the reaction proceeds with high yields in the absence of strong base or Lewis acid catalyst under mild reaction conditions. Depending on the state of steric hindrance in the amine, the reaction products are a double Michael addition product or a so-called vicarious Michael addition reaction product.

  • Publication number: 20060155103
    Abstract: What is disclosed relates to polymers that resist dissolution in organic solvents, are vasodilators, and are tunable explosives. These polymers also form solvent resistant coatings and solvent resistant fibers as well as bonding materials.

  • Publication number: 20050256032
    Abstract: A process for forming a conjugate of a polyoxyalkylene polymer, such as polyethylene glycol, with a compound containing an amine group(s) and/or a sulfide group(s) by reacting the compound with an acrylate terminated polyoxyalkylene, such as polyethylene glycol terminated at one end with acrylate or methacrylate and terminated at the other end With a methoxy group. The reaction is believed to be a Michael addition. When the compound contains primary amine groups, such as the surface primary amine groups of a PAMAM dendrimer, it is usually desirable to convert the primary amine groups to secondary amine groups before the reaction with the acrylate terminated polyoxyalkylene.
