Reactions of Trithiocyanuric Acid with Oxiranes. l. Synthesis of Polyetherols

摘要

Reactions of trithiocyanuric acid with a large excess of ethylene oxide and propylene oxide in DMF solution and in the presence of triethylamine as catalyst were carried out. Trifunctional polyetherols containing an s-triazine ring were prepared. The structure of the products was confirmed by using elemental analysis, ~1H-NMR and IR techniques. Some of the physical properties and thermal stability fo polyetherols were analyzed.
