Abstract

During the curing of a thermosetting resin, the polymer chain lengths increase, the viscosity changes and the sample becomes completely insoluble at high conversions. The determination of the molecular self-diffusion coefficients presents a challenging problem, though it has been studied with the free-volume theory. the Adam-Gibbs theory of cooperative rearrangement, and the pulsed-gradient spin-echo NMR method. To study the diffusion-controlled curing kinetics in order to optimize and control the processing conditions of thermosetting systems and the properties of final products, a convenient method for estimating the cure-dependent diffusion coefficient is very important.
