Communication: A new H-1-NMR imaging method, in which the relaxation time provides the contrast, is demonstrated to be suitable for investigating the effect of shear bands-strongly localized inhomogeneities of the plastic deformation-on the local mobility of polymeric materials in the solid state. The immobilization of a shear band in cold-drawn polycarbonate (PC) is visualized for the first time. In addition to a description of the experiment, results for PC are reported, showing, for example, that the phenylene motion is more affected by the strain that the methyl motion.
