We have investigated the structural consequences of plastic deformation of glassy polymers by solid-state nuclear magnetic resonance spectroscopy. The plastic deformation of glassy polymers, like that of other amorphous solids, presents a challenge to materials science. In spite of considerable research efforts, the elementary processes of deformation in polymer glasses have not yet been identified. Recent progress in solid-state NMR spectroscopy has greatly enhanced the possibilities to characterize the structure of amorpous solids. The application and adaption of novel NMR techniques to deformed, anisotropic samples is discussed, and recent results will be presented.
