Summary

Stress-induced crystallization occurs when one uniaxially draws amorphous poly(ethylene-2,6-naphthalene dicarboxylate) (PEN) films at a certain temperature, drawing ratio and speed. The rigid amorphous fractions of the PEN samples were measured by differential scanning calorimetry (DSC), and their oriented amorphous fractions were detected by wide angle X-ray diffraction (WAXD). It has been shown that there is a close correlation between these two amorphous fractions.
