Manifestation of the morphological features of polydiallylisophthalate in proton magnetic resonance spectra

Abstract The possibility of using the wide line NMR method for investigating the polymerization of diallylisophthalate is demonstrated. The presence in the spectrum of three components reflects the structural heterogeneity of the system. Change in the intensity of the components in the course of heating makes it possible to evaluate the content of the monomer and the weakly crosslinked and densely crosslinked phases during the formation of the crosslinked polymer.
