The Application of in Operando Liquid State NMR on Macromolecular Material Characterization

Abstract

With the shift toward the study of systems in operando and with increasing sensitivity, in operando nuclear magnetic resonance (NMR) is becoming more and more widely used in the field of polymer materials. In operando liquid state NMR provide mechanistic and kinetic information on polymerization reactions with the needless for stable labeling isotope, fast analysis, wide application range and maintaining intact samples. In addition, using the hyphenation of other characterization methods with in operando NMR spectroscopy is one of the most powerful methods for the separation and structural elucidation of unknown compounds and molecular compositions of mixtures by designing a suitable probe. In operando NMR spectroscopy will remain an indispensable and versatility tool in macromolecular science for years to come.
