The effect of solvent, DMF, and hydrophilic polymer on the hydration melting behavior of Tae Kwang polyacrylonitrile-based copolymer (T-PAN) was investigated by DSC measurement. The melting temperature (T,) of T-PAN was sharply lowered by incorporating water under autogenous pressure, but leveled of
## Abstract It has been proposed that during the stabilization of polyacrylonitrile fibers, the reaction is initiated in the amorphous region and then propagates to the ordered region. However, the evidence is unsatisfactory, and some is quite controversial. It has been confirmed in this study thro
