(a) Three-dimensional wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering patterns (SAXS) profiles of P4HB during cooling at a rate of 7 °C/min. (b) Correlation functions obtained after non-isothermal crystallizations of P4HB from the melt state performed at cooling rates of 3 and 10 °C/min. (c) SAXS correlation functions calculated at the indicated temperatures during the cooling run (3 °C/min) of a melted P4HB sample.
