When a sound wave is reflected by a multilayered system, minima of the reflection coefficient corresponding to the propagation of surface waves within the system are observed. We carried out reflectivity measurements on immersed plates made up of two grafted polymers, polyamide 12/poly(ethylglycidyl methacrylate). The experimental curves obtained are discussed and compared with the theoretical predictions to determine the characteristics of the interface between the two polymers.
