Latest Patents

Cheng-Wei Tsai's latest patents include innovative methods for preparing polyurethane prepolymers. One of his patents describes a process that does not require toxic isocyanate monomers, which are typically manufactured using harmful phosgene. Instead, he utilizes epoxy resin and carbon dioxide as major raw materials to create cyclic carbonates. These cyclic carbonates are then reacted with functional group oligomers. The process involves using amino groups from hydrophilic or hydrophobic diamine polymers to perform ring-opening polymerization. Microwave irradiation is employed to efficiently synthesize amino-terminated polyurethane prepolymers. The resulting product can be coated onto fabric surfaces, which are then treated with UV radiation to create long-lasting hydrophilic or hydrophobic polyurethane fabrics.
