The article presents the research into the phase transformation characteristics in the semirigid polymer (poly-para-phenilen-oxadiasol (POD)) which are analyzed by using some physical-chemical methods. It discusses the determined temperature intervals during the phase transformation due to the polymer macromolecular chain structure. The possible manifestation of the crystal structure in its two types is considered. Competing phase transformation characteristics as well as different POD destruction processes are analyzed. Values of the thermodynamic parameters of these processes were calculated.
