The dataset contains information on isothermal crystallisation of Poly(hydroxybutyrate-co-valerate) – PHBV – systems performed at different temperatures. The data was collected using Fourier Transform Infrared Spectroscopy (FTIR), using poly(hydroxybutyrate) – PHB – as well as PHBV systems of various hydroxyvalerate (HV) content – 7, 12, and 21 mol%. The temperature range span from ambient temperature to 150 °C. Full details about this dataset can be found at https://doi.org/10.5285/cfcc0e31-e2ce-450b-a292-3427de06a687
