Introduction

Jang Hyun Choi is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of materials science, particularly in the development of innovative resin compositions. With a total of 5 patents to his name, his work focuses on enhancing the properties of synthetic materials for various applications.

Latest Patents

One of his latest patents is a low gloss ASA-based resin composition that exhibits excellent weatherability and heat resistance. This composition is achieved by blending a general SAN copolymer, a heat-resistant SAN copolymer, a crosslinked aromatic vinyl compound-cyanide vinyl compound copolymer, and an amorphous inorganic material with large diameter and extra-large diameter ASA graft copolymers. The resulting resin composition is particularly useful in manufacturing high-quality molded articles, as it ensures uniform gloss characteristics while maintaining excellent impact resistance, heat resistance, flowability, and weatherability.

Another significant patent involves a synthetic styrene resin composition designed for environment-friendly window frames. This composition comprises a tetrapolymer of acrylic rubber-styrene monomer-butadiene rubber-vinyl cyanide monomer and a high molecular weight styrene-vinyl cyanide copolymer. Unlike traditional polyvinyl chloride (PVC) products, the window frames made from this synthetic resin are recyclable, contributing to a reduction in harmful chemical emissions during disposal. Additionally, this resin composition allows for the production of weather-resistant and colorable products without the use of toxic thermal stabilizers.
