This project mainly exploratorily studied that polyurethane was produced via condensation reaction between polyhydroxylated compounds and methyl carbamate, which was firstly synthesized by dimethyl carbonate and amines. The process is a green route because it turns away the synthesis and the utilization of toxical isocyanic acid ester.
