Title: Hee Ryoung Koo: Innovator in Polymer Manufacturing

Introduction

Hee Ryoung Koo is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of polymer manufacturing, particularly in the development of ethylene-propylene-diene terpolymers. With a total of 4 patents to his name, Koo's work has implications for various applications, including fuel cells.

Latest Patents

One of Koo's latest patents is focused on the manufacturing method for an ethylene-propylene-diene terpolymer. This innovative method involves a polymerization step that subjects an organic chelate compound forming a coordinate bond, a vanadium-based Ziegler-Natta catalyst, an organoaluminum compound, and ethylene, propylene, and diene monomers, along with a solvent, to polymerization in a reactor. The process includes a separation step to recover residual catalysts and unreacted monomers from the stream discharged from the reactor. Additionally, an acquisition step is implemented to recover the solvent from the stream deprived of the residual catalysts and unreacted monomers, ultimately acquiring the ethylene-propylene-diene terpolymer.
