Figure represents WAXS film pattern of as-spun filaments made from the plastic-grade polymer. Continuous Debye-Scherrer reflection rings of planes (110), (040), (130), (111), (31) (041) are visible. This means that the structure is isotropic and consists of spherulites composed of
α-monoclinic crystals, which are oriented in different directions. More details in Gregor-Svetec, p. 959
