“…At room temperature the helix concentration is 1.5 to 2.0 times lower than at 100 K [10]. It was found that for Nylon 6 and PP the concentration of the helices in amorphous zones at 100 K varied from 60% to 90%.…”

“…Assuming the lack of conformational disturbance within crystallites (CCr = Cn) one obtains Since the degree of the crystallinity is Z = (Ccr / Co), and near the melting temperature all helices within amorphous regions are destroyed (11 =Cam.rI./Cam= 0), one obtains [10] =--L--.
