Trifuntional Oligoetherols and Polyurethane Foams with Carbazole Ring
Abstract: The method of synthesis of trifuntional oligoetherols with carbazole ring from 9-(2,3-epoxypropyl)carbazole and die- thanolamine and oxiranes like ethylene and propylene oxide was presented. Structure and some physicochemical prope- rties of the products were described. The oligoetherols were demonstrated as good substrates for synthesis of polyure- thane foams of enhanced thermal resistance. It has been found that the obtained foams are rigid at room temperature and their apparent density was 34 kg/m3- 44 kg/m3. The water uptake was low, maximum to 10.5 mass%. Dynamic thermal analysis of this foams showed that 5% mass loss starts at 200?C - 220?C, while temperature of 50% mass loss was 340?C - 370?C. Concomitantly the increase of compression strength was observed.
