Isothermal curing of a bisphenol A diglycidyl ether-based epoxy-resin-based, using an aliphatic polyamine, has been performed at temperatures between 20 and 60°C. Samples were cured isothermally at various intervals of time, and analyzed by differential scanning calorimetry (DSC). The glass transiti

✦ Synopsis
A procedure is provided for estimating the time to full cure vs. isothermal cure temperature for vitrified epoxy systems. An equation relating the glass transition temperature of vitrified epoxy systems to the time and temperature of cure is developed.

Glass transition temperatures (2'') were obtained vs. isothermal temperature (T,,,,) and time of cure for a polyamic acid/polyimide system. A time-temperature-transformation (TIT) isothermal cure diagram was constructed to include the time to vitrification and "0-2'' curves. A s for epoxies, the rel
The different steps involved in the curing reaction of a purified ether of bisphenol A (BADGE n Å 0) and 1,2-diamine cyclohexane (DCH) were studied with the objective to calculate a time-temperature-transformation (TTT) isothermal cure diagram for this system.

The present article describes a methodology for examining the evolution of the properties vs. cure of a complex thermosetting isocyanate/epoxy reactive mixture which reacts through two consecutive but separable reaction regimes. The methodology is based on the use of the torsional braid analysis (TB
The curing of an unsaturated polyester resin was studied by differential scanning calorimetry (DSC), thermal mechanical analysis (TMA), and Fourier-transform infrared spectroscopy (FTIR). The results are presented in the form of a time-temperaturetransformation (TTT) diagram. The kinetic analysis wa
