Zusammenfassung: | Oligoetherols containing 1,3,5-triazine ring and boron atoms were synthesized in the reactions of N,N,N',N',N",N"-hexakis(2-hydroxyethyl)melamine with boric acid, followed by reaction with alkylene carbonates. The structure and physical properties of the obtained oligoetherols were investigated. The oligoetherols were used for the preparation of polyurethane foams with improved thermal stability and reduced flammability. The properties of obtained foams were compared with those synthesized directly from melamine and alkylene carbonates. Keywords: melamine, alkylene carbonates, boric acid, esterification, hydroxyalkylation, oligoetherols, polyurethane foams, properties. Oligoeterole z pierscieniem 1,3,5-triazynowym i atomami boru otrzymywano w reakcjach N,N,N',N',N",N"-heksakis(2-hydroksyetylo)melaminy z kwasem borowym a nastepnie z weglanami alkilenowymi. Zbadano strukture i wlasciwosci fizyczne wytworzonych oligoeteroli. Uzyskane oligoeterole zastosowano do otrzymania pianek poliuretanowych o zwiekszonej odpornosci termicznej i zmniejszonej palnosci. Wlasciwosci tych pianek porownano z cechami pianek otrzymywanych bezposrednio z melaminy i weglanow alkilenowych. Slowa kluczowe: melamina, weglany alkilenowe, kwas borowy, estryfikacja, hydroksyalkilowanie, oligoeterole, pianki poliuretanowe, wlasciwosci. |
