MOST crystalline polymers exhibit discontinuous X-ray diffraction effects at small angles indicative of a structural discontinuity of about 100 A., which appears to be a basic feature of these materials1. In spite of much research in this field, there is no fully satisfactory explanation of this phenomenon. In our present work an unexpected possibility of interpretation has presented itself.
