Preparation of polyetherols with pyrimidine rings by reaction
New method of synthesis of polyetherols with 1,3-pyrimidine rings by the reaction of 6-aminouracil (6-AU) with excess of propylene carbonate (PC) catalyzed by 1,4-diazabicyclo[2.2.2]octane and potassium carbonate is presented. The structures of products were analyzed by IR, 1H NMR and MALDI ToF techniques. Some physical properties of prepared polyetherols were investigated. Among other things, they show improved thermal stability.
