Title: Innovations of Soonjong Kwak in Graft Copolymerization
Introduction
Soonjong Kwak is an accomplished inventor based in Troy, NY (US). He has made significant contributions to the field of polymer science, particularly in the area of graft copolymerization. His innovative work has led to the development of a unique process that enhances the properties of polymers through grafting techniques.
Latest Patents
Soonjong Kwak holds a patent for a process titled "Graft copolymerization in supercritical media." This patent describes a supercritical graft copolymerization process that involves several key steps. The process includes adding a polymer into a high-pressure reactor, introducing a free radically polymerizable monomer, and incorporating a free radical polymerization initiator. A sufficient amount of a supercritical solvent is then added to dissolve at least a portion of the polymer and the monomer when supercritical conditions are achieved. The reactor is heated and pressurized to reach supercritical conditions for a time sufficient to effect graft copolymerization on the polymer. The reaction pressure typically ranges from 70 atm to 200 atm, and the temperature ranges from 50°C to 90°C. The supercritical solvent used in the examples is carbon dioxide, although other supercritical solvents can also be applied. The process has been demonstrated with polyolefins, particularly polypropylene and poly(vinyl chloride), using monomers such as styrene and acrylic acid.
