The very versatile physico-chemical tool, NMR spectroscopy, has a wide range of applications for both industrial and academic purpose. Base on physics, NMR methodology has contributed not only to investigation of chemical structure and dynamics but also to the magnetic resonance image in biological system. Multinuclear magnetic resonance measurement enables us to get the useful chemical information on nearly every element in the Periodic Table in a qualitative way. Recent development techniques such as Q-NMR as well as homo/hetero ERETIC give us to determine the absolute concentration of specific nuclei of the given molecules in a ppm level. These quantitative methods have the advantage over the other analytical tools in that there is no need to do the delicate pre-treatment experiment before measurement. Along with these analytical applications, 2-dimensional separation methodology in NMR [DOSY, ROSY] similar to chromatography can be now utilized in order to figure out the detailed structure of each component in the mixture and morphology of the polymer. In this presentation I will show how the various solution and solid NMR techniques can be applicable to real polymers in order to solve the current industrial technology issues in regard to colorless polyimide, photoresist, polyamide elastomer, which are important to foldable display, next generation car as well as eco-friendly polymer development.
