Molecular chain di β usion in polyethylene crystals is studied using carbon-13 NMR longitudinal relaxation. Conventional slow-cooled polyethylene samples have been treated by means of electron-beam irradiation in acetylene, which forms crosslinks mainly at the fold surfaces. Following saturation, the
