NONISOCYANATE POLYHYDROXY URETHANES BASED ON THE RAW MATERIAL OF A PLANT ORIGIN

New furfuryl oxypropyl cyclocarbonate (FOPCC)-based nonisocyanate polyhydroxy urethanes (PHU) (FOPCC being a product of recycled renewable raw materials) have been synthesized. The urethane formation reaction was investigated using infrared spectroscopy. The method of differential scanning calorimetry was used for the studies of the kinetics of reactions that form PHU, in particular the urethane-formation reaction and Diels-Alder reaction. It has been shown that FOPCC derivatives can be polymerized in the presence of a complex onium catalyst. Thermally reversible and thermally irreversible cross-linked PHUs have been produced.
