Lv. Mokrushina et Im. Balashova, MODIFIED VERSIONS OF THE UNIFAC MODEL AND THEIR APPLICATION TO CALCULATING THERMODYNAMIC PROPERTIES OF POLYMER-SOLUTIONS, Russian journal of applied chemistry, 70(6), 1997, pp. 884-891
New versions of the UNIFAC model (UNIFAC-I and UNIFAC-II) are proposed
for calculating phase equilibria in monomer-solvent-polymer systems.
The modified versions and the UNIFAC-FV model are used for predicting
liquid-vapor equilibria in 14 binary, ternary, and quaternary systems
containing the synthesis products of styrene and ABS plastics over the
temperature range 353-413 K. All the modifications account for the co
ntribution associated with the change in volume caused by mixing.
