Abstract

Approximately 80% of synthetic polymers for commercial use are crosslinked. Yet, there are very few techniques which reveal the nature of the crosslink structure of these polymers. This article reviews the utility of NMR for the characterization of the type, number and distribution of crosslinks in polymeric materials. It discusses the theory and experimental ramifications of this unusual application of NMR. This is the first article directed specifically towards developing an understanding of this aspect of NMR. It summarizes all aspects of solution and solid state NMR including chemical shift and relaxation measurements for the study of crosslinking. Due to the recent developments in solid state NMR and deuterium NMR, our understanding of the crosslinked structure of polymers has been substantially increased through NMR. It is important that an appreciation of the developing potential of high resolution solid state NMR be recognized so it can be used in the future.
