  • Nonisocyanate polyurethanes: green solutions

    The practical application of NIPU based on epoxy-amine compositions and five-membered CCs in coatings, sealants, adhesives, etc. was largely developed back in the USSR by O. Figovsky &V. Stroganov. Opportunities for optimizing the production of the key component of NIPU, cyclic carbonate, using carbon dioxide are considered. The article discusses sustainable synthesis routes for NIPC for industrial applications. An overview of solutions for the production of foam materials based on non-isocyanate polyurethanes is given.

    Keywords: nonisocyanate polyurethanes, oligomeric cyclocarbonates, green solutions
