Notizen:
Proton magnetic resonance studies of polyethylene have been extended. The relationship of the rigid fraction (NMR) to the crystalline fraction is discussed, and a case is presented for the relative importance of the rigid fraction (or its complement, the mobile fraction). When the polymer has been swollen by low molecular weight solvents, the NMR spectra yield rather direct evidence that the rigid, and presumably crystalline, regions are unaffected. The nature of the molecular motion is discussed in terms of a model, and it is shown that NMR data imply a rather general type motion.
