Title: Innovations of Roger Bruce Harding in Cellulose Ethers
Introduction
Roger Bruce Harding is an accomplished inventor based in Memphis, TN (US). He holds 2 patents that focus on advancements in cellulose ethers and their preparation methods. His work has significantly contributed to the field of materials science, particularly in the processing of cellulose.
Latest Patents
One of Harding's notable patents is centered around the method of preparing cellulose ethers. The invention reveals that the solution rheology of cellulose ethers can be enhanced by mercerizing and recovering cellulose pulp prior to their preparation. For instance, the viscosity of carboxymethyl cellulose (CMC) derived from mercerized cellulose pulp is markedly higher than that from non-mercerized pulp. The method involves obtaining mercerized and recovered cellulose pulp and converting it into cellulose ethers. This innovative approach can be applied to various types of cellulose pulps, regardless of their initial viscosities.
Career Highlights
Harding is associated with Bki Holding Corporation, where he continues to explore and develop new methodologies in cellulose processing. His research has led to the discovery that mercerized cellulose pulp contains a higher percentage of crystalline cellulose II, which enhances its properties compared to non-mercerized pulp. This advancement not only improves the quality of cellulose ethers but also contributes to the production of cellulose floc with greater bulk density.
Collaborations
Harding has collaborated with notable colleagues, including Susan L. H. Crenshaw and Paul Eugene Gregory. Their combined expertise has fostered a productive environment for innovation and research in cellulose applications.
Conclusion
Roger Bruce Harding's contributions to the field of cellulose ethers demonstrate his commitment to innovation and excellence. His patents reflect a deep understanding of material properties and processing techniques, paving the way for future advancements in the industry.
