Application of reactive solvents of melamine for synthesis of polyetherols with perhydro-1,3,5-triazine rings



The application of reactive solvents (RSs), namely hydroxymethyl derivatives of acetone for digestion of isocyanuric acid, which is insoluble in most organic solvents except for DMSO, makes the substrate available for further conversions. At this step, the incorporation of perhydro-1,3,5-triazine ring into RS takes place. The obtained solutions were used for synthesis of polyetherols containing perhydro-1,3,5-triazine rings in reaction with oxiranes: ethylene and propylene oxides. The polyetherols were then used to obtain foamed polyurethanes with enhanced thermal stability. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
