Abstract

Residual monomer, constrained and unconstrained, and pendant double bonds have been assayed by CPPEMAS13C NMR during the postgelation stages of the cure of ethylene glycol dimethacrylate. A simulation using a kinetic gelation model fitted the experimental values well and was extended to make predictions about the pregelation stage and the size and distribution of monomer pools. Estimations of cure by DSC did not correlate linearly with residual unsaturation, though they did so during the cure of tetrakis(ethylene glycol) dimethacrylate.
