Title: Kuo Y Chang: Innovator in Polymer Chemistry
Introduction
Kuo Y Chang is a prominent inventor based in Midland, MI (US). He has made significant contributions to the field of polymer chemistry, holding a total of 5 patents. His work focuses on innovative methods for modifying and utilizing polyethylene glycol ethers and organosilanes.
Latest Patents
One of Kuo Y Chang's latest patents involves the cleavage of polyethylene glycol ethers by hydrolysis. This process allows for the transformation of high molecular weight polyethylene glycol monoethers into lower oligomeric reaction products. This is achieved by contacting a mixture of the high molecular weight polyethylene glycol monoether and water with a hydrolytic cleavage catalyst, such as alumina, at elevated temperatures. Another notable patent pertains to novel .beta.-isocyanato organosilanes. This invention provides a method for preparing .beta.-isocyanatoethoxy silanes by reacting a 2-oxazolidinone with a halosilane to form a unique intermediate silyl-2-oxazolidinone product. The intermediate is then subjected to heat under reduced pressure, converting it into a .beta.-isocyanatoethoxy silane. These difunctional monomeric products serve as valuable starting materials for various silicone and polyurethane prepolymers and polymers.
