The density and refractive index were determined for four binary mixtures of dimethoxymethylphenyl-silane with dimethyldimethoxysilane, dimethyldiethoxylsilane, methylvinyldiethoxysilane and ethenyltrimethoxysilane at different temperatures T= (298.15, 303.15, 308.15, 313.15 and 318.15) K and atmospheric pressure using a DMA4500/RXA170 combined system. The corresponding derived properties were computed from the experimental data. The results were fitted by means of the Redlich-Kister equation and used to estimate the binary interaction parameters and standard deviations. The factors that affect these excess quantities have been discussed. (C) 2016 Elsevier Ltd.
