Polylaurylmethacrylate in bidimensional mixtures with low and high molecular weight substances: effect of the chain mobility on mutual miscibility

Bidimensional two-component mixtures of polylaurylmethacrylate with polyoctadecylmethacrylate, polymethylmethacrylate and stearic acid were studied in the 15–30 °C temperature range at the air-water interface, in order to determine the effect of the state of the hydrophobic side chains on the bidimensional miscibility.We showed that bidimensional miscibility depends on whether the two components have the same interfacial orientation, and that the fluidity of the polymer side chains also plays a very important role.
