Abstract

Effects of conversion and temperature on the isothermal relative rigidity and isothermal physical aging rate of a new liquid dicyanate ester/polycyanurate material are studied in the glassy state using a dynamic mechanical technique. The 'anomalous' maximum in isothermal relative rigidity with increasing conversion correlates with the glass transition/glass boundary, whereas gelation is found to cause a change in slope in the isothermal relative rigidity versus Tg contours. The minimum in the isothermal physical aging rate versus conversion occurs approximately 150°C below Tg and does not correspond to the β-process. The experimental results are summarized in a TgTP diagram which is a framework for understanding the relationships between transitions and material properties.
