We have studied the tensio‐active properties of acrylate diesters at the oil‐water interface. Measurements of the interfacial tension indicate that the molecules are subsequently adsorbed at the interface. The amphiphatic compounds in the monolayer can be polymerized and cross‐linked by UV irradiation. The gelation process of the two‐dimensional system has been studied by measuring the shear mechanical properties. We observed a clear transition from a viscous solution to a cross‐linked gel state. The two‐dimensional films behave like rubber elastic systems. The elasticity depends strongly on the concentration of the cross‐linking agent. The polymerisation of mixed films of monoacrylates and diacrylates can be used to built up two‐dimensional structures with defined rheological properties.
