Cure Studies of PMDA-ODA-and BTDA-ODA-Based Polyimides by Fluorescence Spectroscopy... [Pg.30]

Dielectric spectroscopy techniques (3) represent an exception to this limitation. In fact, Senturia et al. (4) recently described a microdielectrometric method for in situ measurement of epoxy cure. Using a novel microdielectric probe, they studied isothermal cures of digylcidyl ether bisphenol-A (DGEBA) epoxy in which the low-frequency dielectric relaxation time, r, is correlated with the bulk viscosity (4). In this paper we report preliminary results on the utilization of a viscosity-dependent fluorescence probe as an alternative (and possibly complementary) new approach with potential for in situ monitoring of epoxy cure kinetics. We also report the observation of a unique fluorescence "self-probe capability of tetraglycidyl-diaminodiphenyl methane (TGDDM) epoxy which has not been reported previously. [Pg.246]
