Abstract

Dynamic mechanical behavior of polycarbonate has been compared with that of polyester carbonate. The nature of mechanical relaxations in these materials is discussed. The results indicate that the energy requirements for the motion of ester groups are not significantly different from those of the carbonate units.

Zusammenfassung

Das dynamisch-mechanische Verhalten von Polykarbonaten wurde mit dem von Polyesterkarbonaten verglichen. Die Natur der mechanischen Relaxationen in diesen Materialien wird diskutiert. Die Ergebnisse zeigen, daß der Energiebedarf für die Bewegung der Estergruppen nicht signifikant verschieden von dem für die Karbonatgruppe ist.

Резюме

Проведено сравнение динамического механического повед ения поликарбоната и полиэфирного карбо ната, а также обсужден а природа механических релакс аций в этих материалах. Результа ты исследований пока зали, что энергия, необходимая для пере-мещения сложнозфирных групп, мало отличается от та ковой для карбонатных звеньев.
