## Abstract In order to obtain some insight into the structure of an ultrahighβmolecularβweight polyethylene sample, ^13^C CP/MAS NMR experiments have been carried out at temperatures from 23 to β108Β°C. The peak for the crystalline component moves upfield with a decrease in temperature, which is co
## Abstract Changes in morphology and chain dynamics of a series of drawn gelβspun UHMWPE fibers were investigated by 1D and 2D ^1^H, ^13^C and ^129^Xe NMR spectroscopy. The dependence of the rms oscillation angle for the internuclear proton spin pairs around the chain axis can be evaluated from ^1
