Light Scattering Study of the Annealing of Drawn Polyethylene

Abstract
Low‐angle light‐scattering patterns are obtained for stretched polyethylene films which are annealed both with and without the constraint of constant length. The effects of stretching temperature,annealingtemperature,temperature of measurement, and degree of elongation are studied. Morphological changes in superstructure are found which parallel changes in crystal orientation.
