Spatially resolved NMR in polymer science

Selected applications of spatially resolved NMR are presented, which demons trate the use of the method for investigating applied topics relevant to po lymer and materials science. Examples are given for imaging of rigid, soft, and fluid matter. They include characterization and interpretation of elec trical aging in poly(ethylene), cross-link density at the interface of covu lcanized elastomer sheets, and cross-filtration in hollow-fiber filler modu les. A novel NMR dectector, the NMR-MOUSE, has been developed for process a nd quality control by relaxation measurements. Its use for non-destructive determination of the glass-transition temperature by room temperature measu rements on elastomer samples is demonstrated.
