Abstract

Isothermal physical aging deep in the glassy state and its effects on thermomechanical properties are investigated as functions of temperature and conversion for a dicyanate ester/ high-Tg polycynaurate material using a dynamic mechanical analysis technique (TBA). The rate of physical aging is monitored by the increase in the modulus with aging time and by the corresponding change in mechanical loss. The effects of aging are observed by comparing thermomechanical spectra of aged and unaged materials. New phenomena are observed which suggest that the effects of aging on the relaxation time distribution are complex but systematic.
