Improved thermally stable oligoetherols from 6-aminouracil,ethylene carbonate and boric acid

摘要

Syntheses of oligoetherols with a 1,3-pyrimidine ring and boron atoms using 6-aminouracil,ethylene carbonate and boric acid has been proposed.The structure of the obtained products were determined by instrumental methods(IR,~1H-NMR and MALDI-ToF spectra).The physicochemical and thermal properties of oligoetherols were examined.The products were characterized by high thermal stability.Based on the tests performed,it was found that oligoetherols obtained from 6-aminouracil,boric acid and ethylene carbonate are suitable for the manufacturing of polyurethane foams with improved thermal stability and reduced flammability.
