Complementary Stereospecific Interaction Between Isotactic and Syndiotactic Polymer Molecules

“…The peaks at 912 and 840 cm À1 are assigned to CH 2 rocking and the peaks at 809 and 749 are due to the C¼O in plane and out of plane bending, respectively. 47 The FTIR spectra obtained for the composites (Fig. 3(b)) has been thoroughly analyzed and it has been observed that there are additional absorption peaks at 564 and 1541 cm À1 .…”

Composites of poly(methyl methacrylate) (PMMA) and Sr 2 TiMnO 6 (STMO) were fabricated via melt mixing followed by hot pressing technique. These were characterized using X-ray diffraction (XRD), thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC), thermo mechanical analysis (TMA) and impedance analyser for their structural, thermal and dielectric properties. The coefficient of thermal expansion (CTE) was measured between 40 C and 100 C for pure PMMA is 115.2 ppm/ C, which was decreased to 78.58 ppm/ C when the STMO content was increased to 50 wt.% in PMMA. There was no difference in the glass transition (T g ) temperature of the PMMA polymer and their composites. However, the FTIR analysis indicated possible interaction between the PMMA and STMO. The density and the hardness were increased as the STMO content increased in the PMMA matrix. Permittivity was found to be as high as 30.9 at 100 Hz for the PMMAþSTMO-50 wt.% composites, indicating the possibility of using these materials for capacitor applications. The thermal stability of polymer was enhanced by incorporation of STMO fillers.
