Latest Patents

One of Jing-Zhong Hwuang's key patents is titled "Polyurethane prepolymer prepared by functional polyurethane prepolymer and application thereof." This patent describes a method for preparing polyurethane prepolymer without the use of toxic isocyanate monomers, which are typically manufactured using harmful phosgene. Instead, his method utilizes epoxy resin and carbon dioxide as primary raw materials to create cyclic carbonates. These cyclic carbonates are then reacted with a functional group oligomer. The process incorporates amino groups from hydrophilic or hydrophobic diamine polymers to perform ring-opening polymerization, enhanced by microwave irradiation. This innovative approach leads to the efficient synthesis of amino-terminated polyurethane prepolymer. The resulting product can be used to manufacture UV cross-linking polyurethane oligomers, which can be coated onto fabric surfaces, providing a durable and hydrophilic or hydrophobic finish.
