“…Measurements for a range of solvents in PS were made. Our results for the solvent activity and activity coefficients correlate well with previously published literature results1, 13, 14 for benzene, chloroform and cyclohexane. As noted above, the determination of χ is a more stringent test of the method.…”

“…The sorption of organic vapours by polystyrene has been studied by Saeki and co‐workers13 who found that precise values of activity coefficients could be attained with short equilibration times of the order of 10 min. Wong and co‐workers14 applied this technique to the sorption of three solvents by polystyrene and found that accurate results could be obtained rapidly. Activity coefficients of solvents in a series of elastomeric polymers were measured by French and Koplos15 who found reasonable agreement with some literature systems.…”

A quartz crystal microbalance was used as the basis of a vapour sorption apparatus to measure thermodynamic interaction parameters of polystyrene, poly(4-chlorostyrene) and poly(methyl methacrylate) with a number of solvents. The apparatus was shown to give rapid and reliable results by comparison with literature results for poly(dimethyl siloxane). Measurements of activity coefficients and Flory-Huggins interaction parameters were correlated with the solution behaviour of the components and revealed some hitherto unreported effects of the solution concentration in polar systems.

“…The temperature variation of the QCM is reported to be 0.0001 °C up to 45 °C and 0.005 °C up to 110 °C . One disadvantage of this technique is the error due to the adhesion of the polymer to the crystal, which leads to hysteresis . As a polymer must always be solvent coated on the crystal, this technique cannot use neat polymers.…”

Polymer coatings may have different structures owing to possible plasticization, which may result in overestimated sorption values, as a plasticized polymer could sorb more than a neat one.…”

Techniques to measure sorption and migration between small molecules and packaging. A critical review

The mass transfer parameters diffusion and sorption in food and packaging or between them are the key parameters for assessing a food product's shelf-life in reference to consumer safety. This has become of paramount importance owing to the legislations set by the regulated markets. The technical capabilities that can be exploited for analyzing product-package interactions have been growing rapidly. Different techniques categorized according to the state of the diffusant (gas or liquid) in contact with the packaging material are emphasized in this review. Depending on the diffusant and on the analytical question under review, the different ways to study sorption and/or migration are presented and compared. Some examples have been suggested to reach the best possible choice, consisting of a single technique or a combination of different approaches.
