Abstract
Observations by transmission electron microscopy and electron diffraction experiments are reported which suggest that molten polyethylene films with a thickness of about 200 Å have a structure similar to that of a liquid crystal. The molten films consist of folded chain molecules the axes of which are aligned normal to the plane of the film. Solidification of the film results in the formation of large polyethylene single crystals (diameter 0·4 mm or more).Keywords
