Title: **Charles H. Blevins: Innovator in Polymer Chemistry**
Introduction:
Charles H. Blevins, a notable inventor based in Beacon, NY, has made significant contributions to the field of polymer chemistry, holding a total of nine patents. His innovative work encompasses the development of novel compositions that have advanced the production and application of polyurethane foams and other polymer materials.
Latest Patents:
One of his latest patents includes "Silicone Polyether Copolymers and Polyurethane Foams Prepared Therefrom." This invention presents unique silicone/polyether block copolymers that serve as surfactants in various classes of polyurethane foam production. The conventional copolymers typically feature a polysiloxane backbone with pendant polyethers. In contrast, Blevins' work introduces a reverse structure, where siloxane pendants are attached to a polyether chain. These non-hydrolyzable polysiloxane polyoxyalkylene copolymers, characterized by a narrow molecular weight and compositional distribution, are free of unreacted polyether or non-modified silicone oil diluent. The surfactants derived from this patent are valuable in different urethane foam systems and exhibit aqueous wetting properties.
Another significant patent is related to "Olefin Polymer Compositions Containing Polyorganosiloxanes and the Use." This invention revolves around olefin polymer compositions that can be extruded into film materials exhibiting improved stability and optical properties. Specifically, it focuses on compositions containing polyorganosiloxanes with hydroxyl functionalities, enhancing their usability in various applications.
