“…These materials are thermally unstable and, when heated above 120 C, undergo degradative dehydrochlorination. 8 About 170 C, it is observed a significant change in the polymer's original, highly ordered structure, which indicates the breakage of CH 2 bonds in the polymer chain and the expansion of the carbon-halogen bonds (C-Cl), which leads to the elimination of the halogen atoms at sites along the polymer chain. 4 All the prepared samples show appreciable weight losses of about 16, 18, 15, and 16%, respectively, at 180 C. The loss of approximately half of the chlorine atoms from the polymer chain also results in significant changes in the stability of polymer electrolyte.…”
