Title: The Innovations of Frederick Bernhard Kassell
Introduction
Frederick Bernhard Kassell is a notable inventor based in Lake Jackson, TX (US). He has made significant contributions to the field of chemical engineering, particularly in the development of high molecular weight polycarbonates and polyelectrolyte solutions. With a total of 2 patents, Kassell's work has had a meaningful impact on various industrial applications.
Latest Patents
Kassell's latest patents include innovative methods for producing high molecular weight polyhalobisphenol polycarbonates. This process involves adding phosgene to a polyhalobisphenol in the alkali metal phenate form, resulting in the formation of chloroformates of the bisphenol. An activated pyridine is then introduced to generate a high molecular weight polycarbonate with an inherent viscosity ranging from about 0.4 to about 0.9. Additionally, he has developed a method for converting alkenoic acid copolymer latexes into water. This method prepares aqueous solutions of anionic polyelectrolytes by combining high solid content alkenoic acid-alkyl acrylate latex with aqueous alkali metal hydroxide, which avoids the formation of high viscosity mixtures that are difficult to process.
