Title: Innovations by Inventor Chandrasen Gajria

Introduction

Chandrasen Gajria is a notable inventor based in Louisville, KY (US). He has made significant contributions to the field of polymer science, particularly in the development of water-swellable crosslinked polymeric microgel particles. With a total of 4 patents to his name, Gajria's work has implications for various applications, including coating compositions.

Latest Patents

One of Gajria's latest patents involves the creation of carboxylic acid containing polymeric microgel particles. These particles are prepared by polymerizing a monomer mixture in aqueous emulsion, which includes about 10-50% by weight of polymerizable carboxylic acid monomers, up to 5% of a difunctional crosslinking monomer, and one or more carboxyl-free relatively water insoluble polymerizable vinyl monomers. The resulting microgel particles are water-swellable and can be used as stabilizers in the preparation of aqueous dispersions of film-forming resins. These dispersions require smaller amounts of organic solvents compared to conventional aqueous dispersions, yielding coatings that exhibit less water sensitivity and improved adhesion.
