Title: Su Jeong Han: Innovator in Polymer Chemistry
Introduction
Su Jeong Han is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of polymer chemistry, particularly in the development of methods for preparing conjugated diene-based polymers and graft copolymers. With a total of 12 patents to his name, Han continues to push the boundaries of innovation in his field.
Latest Patents
Among his latest patents, Han has developed a method for preparing conjugated diene-based polymers. This method involves initiating polymerization while continuously adding conjugated diene-based monomers to a reactor. An emulsifier is added in a divided manner before the initiation of polymerization and when a polymerization conversion rate of 31% to 80% is reached. This innovative approach allows for a reduction in the total usage amount of emulsifiers. Additionally, he has patented a method for preparing a graft copolymer, which includes adding a conjugated diene-based polymer, an aromatic vinyl monomer, and a vinyl cyan monomer. This method enhances polymerization stability, colorability, light resistance, and surface clarity.
