The films of Poly Methyl Methacrylate (PMMA), Poly Ethylene Glycol (PEG) and a blend of these two polymers (PMMA and PEG) have been prepared by using well known solution casting method. The complexation of the prepared polymer blend films have been confirmed by recording the X-Ray Diffraction (XRD) spectra in these samples. Sharp peaks of the XRD patterns appear at 21.80 and 23.40, which indicate that the PEG was completely crystallized during the polymerization process. The humps around 14.20, attributed to the poorly crystallized PMMA. The surface morphology was examined by Scanning Electron Microscopy (SEM). The FTIR spectra of polymer blend (PMMA+PEG) showed several changes in the absorption band positions compared to pure PMMA. As a result, the FTIR analysis confirmed the constitution of both the blend components and the possible interaction between the components. The DSC studies indicate the melting temperature (Tm) and heat flow. The pure PMMA has a broad melting temperature around 152 0C. the melting temperatures (Tm) of PMMA+PEG blend films with different ratios are observed to decrease when compared to pure PMMA. The temperature dependence ionic conductivity follows the Arrhenius rule in the temperature range of 303 to 373 K. DC conductivity studies have shown 3.16X10-4 S/cm for the blend of PMMA+PEG (60:40) at 100 0C.
