Resumen:
We introduce a model to study the diffusion of chains in microporous solids.  The difficulties a chain has to escape from a pore where it is confined is found to strongly depend on the ratio between the chain length and the cage size.  This dynamic effect implies a non standard behavior of the diffusion coefficient.  We found a window effect that can be explained without using any energy argument.
