The monolayers of polymer microgels adsorbed at the liquid interface were studied by dissipative particle dynamics (DPD) simulations. The results showed that compressibility of monolayer can be widely tuned by varying the cross-linking density inside the microgels and their compatibility with the immiscible phases. Meanwhile, the compression of the monolayers leads to the changes in size of the single microgels, and the sizes of the particles reach their values in the solution with the increase compression ratio. The density profiles plotted along the normal to the interface showed a non-monotonous distribution of polymer concentration with a sharp maximum at the interface. The examination of internal order of the microgel monolayer showed a non-monotonous dependency with the increase of the polymer concentration. Finally, the worsening of the solvent quality lead to the quasi 1D-collapse of the microgel monolayer together with the decrease of the interfacial tension.
