  We consider the escape of a flexible, self-avoiding polymer chain out of a
confined geometry. By means of simulations, we demonstrate that the
translocation time can be described by a simple scaling law that exhibits a
nonlinear dependence on the degree of polymerization and that is sensitive to
the nature of the confining geometry. These results contradict earlier
predictions but are in agreement with recently confirmed geometry-dependent
expressions for the free energy of confinement.
