Forbidden reflections from the aramid PPTA—A novel correlation with stacking faults

[摘要] The occurrence of space group forbidden reflections in the X-ray diffraction patterns from the aramid PPTA has been correlated with the presence of stacking faults. The fraction of sample affected by the presence of such faults has also been estimated.
