The isothermal crystallization of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) was evaluated using a range of models namely, Avrami, simplified Hillier, Tobin, Malkin, Urbanovici-Segal, Velisaris-Seferis and Hay. The Hay model was found to generate the best fit, closely followed by the Velisaris-Seferis parallel model, suggesting that primary and secondary crystallization occur concurrently. This work highlights the importance of selecting the most appropriate model for analyzing isothermal crystallization kinetics, especially when high levels of secondary crystallization occur.
