Title: The Innovative Mind of Richard W. Thomas: Pioneering Polymer Stabilization
Introduction: Richard W. Thomas, an accomplished inventor based in Nutley, NJ, has made significant contributions to the field of polymer chemistry with his innovative inventions. His expertise lies in the development of stabilizers for polymer substrates, particularly through his patented work in long chain N,N-dialkylhydroxylamines and esterification processes.
Latest Patents: Richard holds two notable patents that illustrate his inventive prowess. The first patent involves long chain N,N-dialkylhydroxylamines, which serve as highly effective stabilizers for various polymer substrates, especially poly(arylene sulfide) (PPS). This innovative solution extends the processibility of PPS during its high-temperature processing (300° to 425° C.), a challenging task where traditional stabilizers like phenolic antioxidants and amines may fall short. His hydroxylamine derived from di(hydrogenated tallow)amine is especially valued for its superior stabilization characteristics.
The second patent focuses on an esterification process designed to streamline the preparation of rosin esters, polyesters, and polymeric esters. In this invention, aliphatic or aromatic carboxylic acids are reacted with specific alcohols, utilizing a catalytic mixture of calcium hydroxyaryl phosphonate and an organosilicon heterocycle. This innovative approach not only reduces esterification time but also enhances oxidation stability and color quality of the resultant esters.
Career Highlights: Richard W. Thomas has dedicated his skills and knowledge to Ciba-Geigy Corporation, a leading global company in specialty chemicals. His work has played a pivotal role in advancing the development of polymer products, positioning him as a recognized figure in the research and innovation community.
Collaborations: Collaborating with esteemed colleagues such as Ramanathan Ravichandran and Ambelal R. Patel, Richard has bolstered his inventive capabilities, leveraging their collective expertise to bring breakthrough innovations to fruition.
Conclusion: Richard W. Thomas exemplifies the spirit of invention, with his critical patents addressing significant challenges in polymer stabilization. His contributions at Ciba-Geigy Corporation not only demonstrate his exceptional skills as an inventor but also highlight the collaborative nature of innovation in driving the industry forward.
