The chemical and morphological structure of polyhydromethylsiloxane microspheres obtained at various content of the cross‐linker, which were divinylbenzene and 1,3‐divinyl‐1,1,3,3‐tetramethyldisiloxane, was compared. Increasing the content of cross‐linking agent causes large changes in the structure of the side groups of the polymer and cross‐links between the macromolecules, which strongly influences the surface properties of the resulting microspheres. The hydrophilic–hydrophobic properties of the surface of these microspheres were investigated by evaluating their interaction with the model protein and the hydrophobic dye. The presented procedure provides a simple method of controlling the hydrophilic–hydrophobic properties of siloxane microspheres.
