We study theoretically the dewetting of a liquid film intercalated between a flat solid and a weakly crosslinked rubber. The rubber is characterised by a static shear modulus, mu(0) a high frequency modulus, mu(infinity)(>>mu 0) and a relaxation time, T. The film dewets by nucleation and growth of a dry contact zone (radius R(t) at time i) surrounded by a liquid rim collecting the liquid. We expect three regimes: a) at short times (R < R-c1), the rubber behaves like a hard elastic solid (mu = mu(infinity)) and the dissipation is dominated by the liquid rim. We call this fast elastic dewetting. b) at intermediate times (R-c1 < R < R-c2), the rubber behaves like an ultra-viscous liquid. We call this "mixed viscous dewetting" because both components dissipate. c) at long times (R > R-c2) the rubber behaves like a soft solid (mu = mu(0)) and the liquid dissipation is again dominant. We call this slow elastic dewetting.
