In our work the silica gel was modified at three temperatures by the zirconium coupling agents. As a result one obtains monomolecular layer of the zirconate on the silica gel surface. The physico‐chemical properties of this layer and its influence on the modificate properties may be characterized by inverse gas chromatography (IGC) and expressed by both solubility parameters and surface parameters. The influence of the temperature of the modification and the modifier structure on the modificate's properties was examined and discussed. In this paper we looked for the relationships between the solubility parameter δ 2 , its components and surface parameters γ 2 d , K A , K D and S C .
