Synthesis of Aqueous Non-Isocyanate Polyurethane

Abstract:

Cyclic carbonate emulsion was prepared by means of polymerization technology using DOMA (which was synthesized by glycidyl methacrylate and carbon dioxide) and acrylic monomers. Effect of temperature, amount of emulsifier, initiator, DOMA and acrylic acid on properties of the emulsion and the film were studied. It was found that with 4% emulsifier, of which the ratio of OP-10 and SDS was 2:1, and 0.4% initiator, 3.5% acrylic acid, 13.3% DOMA, the temperature was 78°C. Under this condition the performance was the best, and then the aqueous non-isocyanate polyurethane was synthesized by cyclic carbonate emulsion and diethylenetriamine as curing agent. The structure of emulsion and aqueous non-isocyanate polyurethane was characterized by FTIR.
