Abstract
AbstractCrystallization kinetics of the biodegradable and fast crystallizing poly(butylene succinate) is studied, under both isothermal and non‐isothermal conditions. For the isothermal process at temperatures from 75 to 95 °C it is found that the Avrami model successfully describes the transformation kinetics. The non‐isothermal crystallization data obtained at a wide range of cooling rates from 0.1 to 20 °C · min−1 are treated with several models, which include the modified Avrami, the Ozawa, the combined Avrami‐Ozawa, and the Tobin model. The Lauritzen‐Hoffman parameters are estimated from isothermal and non‐isothermal differential scanning calorimetry data, using different approximations for the growth rate and from the effective activation energy equation proposed by Vyazovkin and Sbirrazzuoli. The multiple‐melting behavior has been interpreted in the context of the melting–recrystallization–remelting phenomena.magnified image
