The morphology of melt‐crystallized polyethylene is reported. The samples were crystallized for different times at high temperature to produce early stages of spherulitic growth. Morphology studies using transmission electron microscopy showed that the largest proportion of the early objects was monolayers associated with a giant screw dislocation, and the remaining objects were multilayers. At the basal surfaces of these objects, the traces of the {1 0 0} planes were identified, and the angle between the different planes was found to be 67°30′. © 1999 John Wiley & Sons, Inc.
