Abstract

The solubilities of dichloromethane, diethyl ether, ethyl acetate, nitrobenzene in polyisobutylene (PIB), poly(n-butyl methacrylate) (PBMA), and poly(vinyl acetate) (PVAc) were measured by the piezoelectric quartz crystal microbalance method at four temperatures, (293.2, 313.2, 333.2, and 353.2) K. In this work, three quartz crystals were installed in an equilibrium cell, which enables multiple solubility measurements. The estimated experimental uncertainty was less than 1 % for solvent activity and 6.6 % mass fraction at the lowest solubility region, with a lower uncertainty being found in the higher solubility region. The accuracy of the apparatus was confirmed by comparison of the experimental data obtained in this work with the literature data. The Flory - Huggins equation with the temperature-dependent interaction parameter was used for the correlation of the experimental data with an overall average absolute deviation in activities of 6.5 %.
