Abstract
Specifically deuterated liquid crystal polymers (LCPs) were studied by 2D NMR relaxation spectroscopy. Analysis of the various H NMR experiments provided quantitative information about molecular order and dynamics of the systems. The polymers exhibit typical semicrystalline behavior, manifested by two different motional components. Molecular structure is characterized by a high degree of conformational and orientational order, which strongly correlates to the unusual mechanical properties of these materials. The NMR investigations emphasize the particular advantages of 2D NMR relaxation methods in studying complex chemical systems.Keywords
