High-resolution electron macroscopic images of lamellar single crystal of polyethylene (PE) have been successfully obtained using highresolution electron microscopy (HREM), although so far the feasibility of obtaining HREM images from such a radiation sensitive polymer is still drastically questione
## Abstract Density, heat of fusion and melting temperature data of annealed polyethylene single crystals suggest the existence of a temperatureβdependent pseudoβamorphous surface layer which contains chain folds and free chain ends. In the ideal twoβphase model, one assumes two such amorphous laye
