Dillip K. 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).

  • Polyarylene ethers and polyarylene sulfides containing phosphine oxide group and modified by reaction with organoamine
    Patent number: 5134207
    Abstract: Phosphine oxide-containing polyarylene ethers and sulfides can be reacted with organoamines to form novel graft copolymers (with monofunctional amines) or novel crosslinked thermosetting network compositions (with multifunctional amines). The network materials show desirable resistance to a variety of organic solvents including chloroform.
