Abstract: Isothermal and non-isothermal crystallization kinetics of microbial poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) [P(3HB-3HHx)] was investigated by differential scanning calorimetry (DSC) and 13C solid-state nuclear magnetic resonance (NMR). Avrami analysis was performed to obtain the kinetic parameters of primary crystallization. The results showed that the Avrami equation was suitable for describing the isothermal and non-isothermal crystallization processes of P(3HB-3HHx). The equilibrium melting temperature of P(3HB-3HHx) and its nucleation constant of crystal growth kinetics, which were obtained by using the Hoffman–Weeks equation and the Lauritzen–Hoffmann model, were, respectively, 121.8 °C and 2.87 × 105 K2 when using the empirical ‘universal’ values of U* = 1500 cal mol−1. During the heating process, the melting behaviour of P(3HB-3HHx) for both isothermal and non-isothermal crystallization showed multiple melting peaks, which was the result of melting recrystallization. The lower melting peak resulted from the melting of crystals formed during the corresponding crystallization process, while the higher melting peak resulted from the recrystallization that took place during the heating process.
