Reptation of stars

We consider the stochastic motions of a star-shaped flexible polymer trapped inside a fixed network. We predict : 1° a renewal time Tr for the star conformations which increases exponentially with the molecular mass M, and 2° a logarithmic relaxation of stress. We do not know whether these properties still hold for a homogeneous melt of stars, or not.
