Title: Kenji Tsuruhara: Innovator in Polycarbonate Resin Production

Introduction

Kenji Tsuruhara is a notable inventor based in Kitakyushu, Japan. He has made significant contributions to the field of polymer chemistry, particularly in the production of polycarbonate resins. With a total of 2 patents to his name, Tsuruhara's work has advanced the methods of producing high-quality resin particles.

Latest Patents

Tsuruhara's latest patents include two innovative processes. The first patent is titled "Process for producing polycarbonate resin particles." This process involves producing polycarbonate resin particles from a methylene chloride solution of a polycarbonate resin obtained through the polycondensation of a dihydroxydiaryl compound and phosgene. The method includes continuously supplying the methylene chloride solution to a particle-forming vessel, heating it while maintaining it in a suspended state in water to evaporate methylene chloride, and forming an aqueous slurry containing polycarbonate resin particles. The process also involves subjecting a portion of the resulting slurry to wet pulverization treatment and recycling the treated particles back to the particle-forming vessel.

The second patent is titled "Process for producing aromatic polyester polycarbonate particles." This process similarly utilizes a methylene chloride solution of an aromatic polyester polycarbonate. It involves continuously supplying the solution to a particle-forming tank, heating it in a suspended state in water to evaporate methylene chloride, and forming aromatic polyester polycarbonate particles. Like the first process, it includes wet pulverization treatment of a portion of the resulting slurry and recycling the treated slurry to the particle-forming tank.
