Crystallite orientation in low-density polyethylene and its effect on mechanical anisotropy

Abstract

In an earlier note [1], the results of an investigation on the orientation distribution of crystallites in polyethylene films having different degrees of orientation and fiber symmetry were described and, from visual inspection of the intensity of the 002 reflection, a qualitative comparison with the mechanical data was made. Quantitative measurements of intensity distribution have now been made and from these the orientation distribution of crystallites and their effect on mechanical anisotropy have been evaluated.
