Crystallization behevior of poly(3-dodecylthiophene)

The crystallization behavior of poly (3-dodecylthiophene) (P3DDT) is studied bq differential scanning calorimetry (DSC) under different cooling rates. When the methods of Jeziorny., Ozawa and a new one proposed by our laboratory are applied to describe its nonisothermal crystallization behavior, the new one is confirmed to be the best and convenient. By determining kinetic parameters, the analysis of the nonisothermal crystallization behavior is performed. According to Kissinger method, the crystallization activation energy of P3DDT is also evaluated.
