Abstract
A new class of heterocyclic polymers with cross-linked structure, poly tricycloquinazolines, was synthesized, A study of both thermal and the rmooxidative degradation of model systems testified in the temperature range 300-600 degrees C tricycloquinazoline is the most thermostable among five and six membered condensed heterocycles. The polytricycloqu inazolines based on a 3,3'-dicyano-4,4'-diaminodiphenyl methane exhibi t extremely high thermooxidative stability, and materials on their bas is show good mechanical properties.
