Проведено исследование длительного термоокислительного старения фенолтриа- зиновых полимеров в атмосфере воздуха в изотермических условиях в широком температурном диапа- зоне. Также исследованы порошкообразные образцы полимера методом ТГА. Оценена энергия актива- ции реакции деструкции. Расчетным путем построены зависимости «степень конверсии – время» в изотермических условиях. Показано несовпадение расчетных и экспериментальных кривых, что было объяснено масштабным эффектом.

Long-term thermo-oxidative aging of phenolic triazine polymers in the air in isothermal condi- tions at wide temperature range was researched. Also powder samples of the polymers were researched by TGA-method. Activation energy of the destruction reaction was evaluated. The dependences «conversion – time» in isothermal conditions were built by calculation. The discrepancy between the calculated and experi- mental curves is shown which is explained by scale effect.
