Biobased Cyclic Carbonate Functional Resins and Polyurethane Thermosets Therefrom

DESCRIPTION

This technology introduces a sustainable, non-isocyanate route to producing high-performance polyurethane materials using bio-derived feedstocks. By converting epoxidized natural oils, such as epoxidized sucrose soyate, into cyclic carbonate-functional resins via reaction with carbon dioxide, the system replaces toxic isocyanates with multifunctional amine curing agents. The resulting thermosets combine exceptional mechanical strength, thermal stability, and chemical resistance with a safer, more environmentally responsible formulation. Designed for coatings, adhesives, sealants, and composites, this platform allows manufacturers to meet sustainability and regulatory goals while maintaining the performance and processability of traditional polyurethane systems.
