Title: Innovations of SungJae Na: A Pioneer in Polymer Chemistry
Introduction
SungJae Na is a prominent inventor based in Daejeon, South Korea, known for his significant contributions to polymer chemistry. With a total of nine patents to his name, he has made remarkable advancements in the field, particularly in the development of flame-retarding materials.
Latest Patents
One of his latest patents is focused on a flame-retarding carbon dioxide/epoxide copolymer and the method for preparing it. This innovative method allows for the precise control of molecular weight and chain shape in low-molecular-weight poly(alkylene carbonate). By introducing a phosphorous compound as a chain transfer agent, Na has developed a process that copolymerizes an epoxide compound with carbon dioxide using a trivalent metal complex. The resulting polymer not only exhibits flame-retarding properties but also includes a phosphate or phosphonate group in its chain, enhancing its utility in various applications.
Another notable patent involves the preparation of poly(alkylene carbonate) with controlled molecular weight and polymer chain structure. This invention utilizes a chain transfer agent composed of a compound with an alcohol or carboxylic acid functional group during the copolymerization process. The outcome is a polymer compound that can be prepared in both star-shaped and linear chain forms, making it versatile for use as a coating agent or in mixtures with isocyanate compounds for polyurethane production.
