Abstract:

The nonisothermal crystallization behavior of biocompatible and biodegradable polyester P(BHB-CL) was investigated via differential scanning calorimetry(DSC). Avrami equation, Ozawa approach, and Mo approach were adopted to study the nonisothermal crystallization of P(BHB-CL), and activation energy value of P(BHB-CL) was determined according to the Kissenger method. The results show that Mo approach can be successfully applied to analyze the nonisothermal crystallization process of P(BHB-CL).

Key words: P(BHB-CL); Nonisothermal crystallization kinetics; Differential scanning calorimeter
