Authors propose to express the magnitude of modified filler/polymer interactions by Flory ‐ Huggins χ 23 parameter. We investigated polyether‐urethane/modified silica systems containing different amounts of filler (5, 10,20%wt). Moreover, information on the physicochemical properties of oligomer and modified silicas were presented with the use of the following parameters: • solubility parameter δ 2 , describing properties of the polymer layer; • Flory‐Huggins parameter χ 12 ∞ which describes polymer‐solute or mixture polymer/silica‐solute interactions. These parameters δ 2 and χ 12 ∞ are obtained from Inverse Gas Chromatography experiments. The influence of the IGC experiment temperature, the content of modified silica, the nature of test solute on the evaluated parameters are presented and discussed.
