Blends were prepared using a Brabender preparation station and compression moulding. Characterisation included differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), environmental scanning electron microscopy (ESEM) and atomic force microscopy (AFM). Thermal analysis, AFM and ESEM support the occurrence of a partial compatibilisation. In particular, the DSC results showed that the melting peaks intermediate between those of pure components.
