Title: The Innovative Contributions of Arthur J Yu

Introduction

Arthur J Yu is a prominent inventor based in Stamford, CT, known for his significant contributions to the field of polymer chemistry. With a total of 13 patents to his name, Yu has made remarkable advancements in thermoset compositions and copolymer formulations. His work has had a substantial impact on the development of new materials with enhanced properties.

Latest Patents

Yu's latest patents include innovative compositions for forming poly(oxazolidone/urethane) thermosets. One notable patent describes the reaction of a diepoxide with a mono- or dicarboxylic acid, resulting in a prepolymer that possesses both hydroxy and epoxy groups. This prepolymer, when reacted with a polyisocyanate, yields a poly(oxazolidone/urethane) thermoset composition that is substantially free of isocyanurate linkages. The thermoset features oxazolidone linkages in its backbone, separated by ester linkages, with urethane linkages present in side chains attached to the polymer backbone. Additionally, Yu has developed improved copoly(carbonate/phosphonate) compositions formed by the reaction of a dihydric phenol, a carbonate precursor, and an organophosphorus dihalide. The presence of an effective amount of a chain branching agent enhances the inherent viscosity and melting point of these compositions.
