discontinuities are observed at the glass transitions. The corresponding values of Tg obtained from these results are 94 and 84 °C for the amorphous and liquid-crystalline phases, respectively, in perfect agreement with the DSC results. The correlation lengths estimated from the widths of the mesophase layer peaks are of the order of the extended chain length of the polymer, so that no extensive chain folding
