## 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 **Summary:** By using DSC, ^13^C CP/MAS NMR and SEM, we studied the physical properties and chemical structure of silk fibers grafted with methacrylamide (MAA). At a given MAA concentration, the inverse of fiber weight gain linearly increased with increasing square root of the initiator
