Abstract

Glass transition temperatures (T//g) were obtained vs isothermal temperature (T//c//u//r//e) and time of cure for a polyamic acid/polyimide system. A TTT isothermal cure diagram was constructed to include the time to vitrification and iso-T//g curves. As for epoxies, the relationship between T//c//u//r//e and the time to vitrification is 'S'-shaped. Plots of T//g vs T//c//u//r//e showed that solvent evaporation and chemical reaction are controlled by vitrification.
