Abstract (EN): Solubility diagrams of a series of carboxylic acids in a matrix of linear polystyrene have been measured using a gravimetric method on samples immersed in solvent, as reported earlier [Bernardo G, Vesely D. Eur Polym J 2007;43:938-48]. The results show that the amount Of Solvent, swelling the polymer, reaches an equilibrium saturation which has a unique and reproducible value for each system and temperature. An analysis based on Flory Huggins theory shows that all data presented here can be well interpreted with an interaction parameter in a simple form: chi = a + (b/T). An excellent fit can also be obtained using the van't Hoff equation. Ail analysis based on total and partial (Hansen) solubility parameters has also been investigated.
