With a total of six patents to his name, Hsu's work has had a considerable impact on various industrial applications.
Latest Patents
Hsu's latest patents include a method for producing polyester polyol. This innovative method involves feeding a first antioxidant and a raw material reactant, which includes a polyacid and a polyol, into a reactor. The process subjects the polyacid and polyol to an esterification reaction to form an oligomer, followed by a prepolymerization reaction to obtain a prepolymerization reactant. The method emphasizes monitoring the acid value of the reactants to ensure optimal conditions for the polycondensation reaction, ultimately generating a polyester polyol.
Another notable patent is for a polyurethane adhesive and a mixture used in manufacturing plastic athletic tracks. This adhesive comprises a urethane pre-polymer formed by the reaction between an isocyanate and a polyol. The polyol is selected from polyether polyol and polybutadiene polyol, with a specific molecular weight range. The adhesive's formulation ensures a suitable viscosity and content of the urethane pre-polymer, making it ideal for athletic track applications.
