Title: Billie B Dadgar: Innovator in Polymer Chemistry
Introduction
Billie B Dadgar is a prominent inventor based in Baton Rouge, Louisiana, known for his significant contributions to polymer chemistry. With a total of 17 patents to his name, Dadgar has made remarkable advancements in the field, particularly in the development of novel materials with enhanced properties.
Latest Patents
Among his latest patents, one notable invention is the development of brominated polystyrenic resins. These novel brominated styrenic polymers exhibit superior properties that make them ideally suited for current commercial requirements as flame retardants in thermoplastic polymers. The polymers demonstrate high thermal stabilities in standard Thermal Stability Tests, which significantly reduce the risk of corrosion problems due to the release of hydrogen halide at elevated processing temperatures. Additionally, these polymers possess low color or staining properties and excellent melt flow characteristics.
Another significant patent involves the purification of arylene polyphosphate esters. This process minimizes or prevents emulsion formation and suppresses hydrolytic product degradation during the purification of impure bisphenol-A bis(diphenylphosphate). The method involves creating a hydrocarbon solution of bisphenol-A bis(diphenylphosphate) and impurities in a solvent that includes at least one aromatic hydrocarbon and one paraffinic hydrocarbon. The solution is then washed with water or an aqueous buffer solution, followed by alkaline washing to separate the purified organic phase from the aqueous phase.
