Oligoetherols Obtained from Uric Acid, Glycidol, and Alkylene Carbonates and Their Use to Obtain Polyurethane Foams of Enhanced Thermal Resistance

ABSTRACT

A new method of preparation of oligoetherols containing purine rings from uric acid and an excess of glycidol and alkylene carbonates was presented. The course of reaction was studied at various molar concentrations of glycidol. The structure of the products was established, and some physical properties were measured. The oligoetherols were demonstrated to be useful substrates for rigid polyurethane foams of enhanced thermal stability.
