13C NMR spectrometry has been used to identify and assay residual unsaturation in the cure of ethylene glycol dimethacrylate, and distinguish between monomer molecules and pendant double-bonds. Direct evidence of heterogeneity is provided by the distinction between constrained and unconstrained monomer. The predictions of a simulation using a kinetic gelation model coincide with the experimental estimations. Cure estimated by differential scanning calorimetry does not correlate linearly with residual unsaturation.
