Summary Binary blends of poly(vinylidene fluoride), PVDF, with cellulose acetatebutyrate (CAB) were characterized by using differential scanning calorimetry (DSC), wide angle X-ray scattering (WAXS) and Fourier transform infrared spectroscopy (FTIR). This system was proved to be partially miscible, showing a significant decrease on the thermal parameters (ΔHf and Tm) as well as on the crystallinity index (CI) of PVDF with CAB content on the second DSC run. γ crystalline form of PVDF, which is predominant in the as-cast blends, changed to α form with the first DSC run. In contrast, thermal treatment at 200°C (30 min) on blends containing 40–60 wt. % of CAB caused the γ phase to be predominant, as observed by FTIR.
