Title: Innovations of Sung-Won Ha in Polymer Adhesives

Introduction

Sung-Won Ha is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of polymer chemistry, particularly in the development of adhesive compositions. With a total of two patents to his name, his work has implications for various industrial applications.

Latest Patents

Sung-Won Ha's latest patents include innovative syrup polymer compositions and adhesives derived from them. The first patent describes an acrylic syrup polymer composition created by partially polymerizing a (meth)acrylic monomer mixture in the presence of a thiol chain transfer agent. This process results in a first syrup polymer composition that contains a low molecular weight solute (meth)acrylic copolymer and solvent monomers. The chain transfer agent is then quenched, and further polymerization produces a second syrup polymer composition that includes both low and high molecular weight solute acrylic copolymers, along with optional unreacted solvent monomers. The final product can be photopolymerized to create a pressure-sensitive adhesive.

The second patent focuses on a method for preparing an acrylate adhesive. This method involves partially polymerizing a monomer mixture to create a syrup polymer composition with a high molecular weight solute copolymer. This initial syrup composition undergoes further polymerization to yield a second syrup polymer composition with a low molecular weight copolymer. A crosslinking agent is then added, followed by additional polymerization to produce the final adhesive composition.
