Structural Characterization of PS, PMMA and PS/PMMA Polymeric Blend

The present paper reports the structural characterization of polystyrene (PS), poly methyl methacrylate (PMMA) and their polymeric blend (50PS/50PMMA). The structural characterizations of PS, PMMA and 50PS/50PMMA polymeric blends have been performed through Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). The FTIR spectra of 50PS/50PMMA blend show the ascription of both PS and PMMA bonding which was observed individually in pure PS and pure PMMA samples. In addition, there are no new absorption peaks in the blend spectrum. These observations intimate that in PS/PMMA polymeric blend only mechanical blending takes place and no new chemical bonds are created. The X-ray diffraction pattern of pure PS, pure PMMA and 50PS/50PMMA blend samples emphasize on the amorphous nature.
