The structure of these compounds were established using 1H NMR, FT-IR and elemental analyses. The densities and viscosities were measured at T = (293.15-353.15 K), whereas the refractive index was measured at T = (293.15-333.15 K) and empirical correlations were proposed to represent this study. The decomposition temperatures were determined using a thermogravimetric analyser. The thermal expansion coefficients were also calculated and reported. © 2012 Copyright Taylor and Francis Group, LLC.
