Title: Shigeyuki Yoshida: Innovator in Polymer Technology
Introduction
Shigeyuki Yoshida is a notable inventor based in Ohtake, Japan. He has made significant contributions to the field of polymer technology, holding two patents that showcase his innovative approach to material science.
Latest Patents
Yoshida's latest patents include a process for continuously producing ε-caprolactone polymer. This process involves heating ε-caprolactone under reduced pressure or in an inert gas stream to volatilize unreacted ε-caprolactone from the polymer. The vapor phase is then cooled to recover the unreacted ε-caprolactone, with the recovery amount regulated to be greater than five times by weight the amount of caprolactone dimer. Another significant patent is for styrene-based resin compositions and molded articles thereof. This invention incorporates silicone powder into styrene-based resin, resulting in compositions that exhibit improved impact resistance and sliding properties. The modified resin maintains excellent fluidity and thermostability, making it suitable for various applications, particularly in injection and extrusion molding.
