Oligoetherols and polyurethane foams obtained from melamine diborate

Abstract

The method of synthesis of oligoetherols with 1,3,5-triazine ring and boron was established. The obtained oligoetherol is suitablse to obtaining polyurethane foams (PUFs) of enhanced thermal resistance and diminished flammability. The obtained PUFs can stand long term thermal exposure at 175 °C. The PUFs annealed at 150 and 175 °C showed improved compressive strength in comparison with not exposed to heating.
