Title: The Innovative Journey of Inventor Ben Duh
Introduction: Ben Duh is an accomplished inventor based in Tallmadge, OH, who has made significant contributions to the field of polymer chemistry. With a remarkable portfolio of 18 patents, his work focuses on enhancing the properties of poly(trimethylene terephthalate) (PTT), a widely used polymer in various applications.
Latest Patents: Ben Duh's recent patents reveal his innovative approach to improving the functionality of PTT. One of his notable patents is aimed at the "Reduction of friability of poly(trimethylene terephthalate)." This invention effectively reduces the fragility of crystallized PTT and solid stated PTT by lowering the temperature of quenching water during the pelletizing process to between 32°F (0°C) and 65°F (18°C). Additionally, he enhances the robustness of solid stated PTT pellets through the use of prepolymers with lower intrinsic viscosity or by increasing the IV of the finished product. Another significant patent is the "Apparatus for crystallization of polytrimethylene terephthalate," which describes a vessel designed for continuous fluidized bed flow of pellets in water at temperatures ranging from 65 to 100°C. This innovative approach allows for hot-water treatment of the pellets, increasing their crystallinity to over 35% and enhancing pellet density.
