Nagarjuna Amarnath pursued his Ph.D. from Shiv Nadar University, Delhi, India, with a thesis entitled 'Design, synthesis, and application of biobased polybenzoxazine as a flame retardant and adhesives'. During this period, he chemically modified bio-origin raw materials, which are the biobased building blocks for the synthesis of polybenzoxazine. The application of this thermoset polymer was towards flame retardancy and adhesion. At present, he is a postdoc developing high molecular weight biobased polycondensates exhibiting properties similar to polyethylene-like materials. During this time duration, he is exploring various possibilities for introducing cleavable functionalities into the polymer backbone via polycondensation.
