Experimental density r, refractive index nD and viscosity h data of three   binary systems of poly(ethylene glycol) diacrylate (PEGDA) + ethanol, +   1-propanol, and + 1-butanol were measured at eight temperatures from (288.15   to 323.15) K, with temperature step of 5 K, and at atmospheric pressure. The   experimental data were correlated as a function of PEGDA mole fraction and   temperature. Densities and refractive indices of the investigated mixtures   could be fitted well with exponential function vs. composition, including   temperature dependence of parameters, while in the case of viscosities   polynomial function fits well over a mixture’s composition. In the case of   temperature correlation, all three properties (ρ, lnη and nD) exhibit linear   trend. The viscosity modeling was performed using four models: UNIFAC-VISCO,   ASOG-VISCO, Mc-Allister and Teja-Rice. For application of UNIFAC-VISCO model   interaction parameters of following groups were determined: CH2=CH/CH3,   CH2=CH/CH2, CH2=CH/OH, CH2=CH/CH2O and CH2=CH/COO. Also, in the same way   binary interaction parameters used in ASOG-VISCO of the following groups were   determined: CH2=CH/CH2, CH2=CH/OH, CH2=CH/CH2O and CH2=CH/COO.
