Determination of the Coupling Coefficient C(ν) from the Calculations of the Low-frequency Raman Spectrum in PMMA [PDF]
arXiv, 2015 Using the atom-atom potentials method, we have calculated the low-frequency Raman spectra of molecular crystal model with elements of disorder (Poly-Methyl-Methacrylate) PMMA that has a flexible molecule. Based on the results the coupling factor C(\nu) has been calculated.

Electrostatic charging of non-polar colloids by reverse micelles [PDF]
arXiv, 2007 Colloids dispersed in a non-polar solvent become charged when reverse micelles are added. We study the charge of individual sterically-stabilized poly(methyl methacrylate) spheres dispersed in micellar solutions of the surfactants sodium bis(2-ethyl 1-hexyl) sulfosuccinate [AOT], zirconyl 2-ethyl hexanoate [Zr(Oct)$_{2}$], and a copolymer of poly(12 ...

Dielectric properties of Poly(methyl methacrylate) (PMMA)/CaCu3Ti4O12 Composites [PDF]
arXiv, 2013 Materials with high dielectric constant are in great demand for the miniaturization of electronic devices. More specifically, high dielectric constant polymer-ceramic composites are useful for embedded capacitor applications. A composite consisting of giant dielectric CaCu3Ti4O12 (CCTO) incorporated into the Poly(methyl methacrylate) (PMMA) polymer ...

Fabrication and Characterization of Poly(methyl methacrylate)CaCu3Ti4O12 Composites [PDF]
arXiv, 2013 Composites comprising Poly(Methyl Methacrylate) (PMMA) and CaCu3Ti4O12 (CCTO) via melt mixing followed by hot pressing were fabricated. These were characterized using X-ray diffraction (XRD), thermo gravimetric (TGA), scanning electron microscopy (SEM) and Impedance analyser for their structural, morphology and dielectric properties.
