## Abstract In order to obtain some insight into the structure of an ultrahigh‐molecular‐weight polyethylene sample, ^13^C CP/MAS NMR experiments have been carried out at temperatures from 23 to −108°C. The peak for the crystalline component moves upfield with a decrease in temperature, which is co
