Title: Innovations of Devendra Kumar
Introduction
Devendra Kumar is a notable inventor based in Shakarpur Extension, India. He has made significant contributions to the field of chemistry and materials science, holding a total of six patents. His work focuses on developing advanced materials with high heat and fire resistance properties.
Latest Patents
One of his latest patents involves the synthesis of aromatic cyclotriphosphazenes. In this process, 4-Aminophenoxy cyclotriphosphazenes are reacted with maleic anhydride to produce maleamic acids, which are then converted to maleimides. These maleimides are polymerized, leading to a variety of polymers with high limiting oxygen indices and char yields. These materials are particularly useful as impregnants for fabrics due to their excellent heat and fire-resistant properties. Another significant patent involves the use of aminophenoxycyclotriphosphazenes as curing agents for epoxy resins. The resins are thermally cured in stages, resulting in fire-resistant composites and laminates suitable for aircraft and spacecraft construction.
