Abstract
We discuss the hydrodynamic modes of a thin viscoelastic film of polym eric material at the interface between two Newtonian fluids. The mode dispersion relations and the dynamic structure factor of thermally ind uced (transverse) modes are obtained by the method of fluctuating hydr odynamics utilizing generalized boundary conditions derived for a thin viscoelastic interface. Specific examples appropriate to liquidlike f ilms of entangled polymers are presented, and possible relevance to ex isting experimental studies of dynamic light scattering from insoluble polymeric monolayers is discussed.
