Title: Innovations by Sung Kyou Park

Introduction

Sung Kyou Park is a notable inventor based in Dusan, South Korea. He has made significant contributions to the field of polycarbonate resin technology. With a total of 3 patents, his work focuses on improving the properties and production methods of polycarbonate materials.

Latest Patents

One of his latest patents is a method of preparing polycarbonate resin that enhances thermal stability. This method involves mixing polycarbonate with hydroxy terminal groups and an end terminator at normal temperature and pressure to create a mixture. A melt reaction is then performed on this mixture at temperatures between 250-320°C and reduced pressure to significantly lower the concentration of hydroxy terminal groups in the final polycarbonate resin.

Another innovative patent by Park is a method of producing modified polycarbonate using a spray-crystallizing method. This process includes a melt condensation polymerization that combines transesterification and quick condensation polymerization. The spray crystallization process allows for solid state polymerization without the need for additional drying, milling, or fractionation, thus reducing operational time and costs. This method also enables efficient control over the crystallinity and size of the modified polycarbonate particles, resulting in a high-molecular weight product with uniform physical properties.
