摘要：

Some polymer melts (of high viscosity eta) can wet completely the surface of a non miscible, simple liquid. We discuss here the laws of spreading for a macroscopic droplet of this type, when the internal friction of the droplet dominates. We predict a droplet radius increasing like t(1/4) where t is the spreading time, or equivalently a droplet curvature decreasing like t(-1). The droplet should be surrounded by a precursor him, which is not discussed in the present note.
