The effect of excluded-volume interactions on the reptation dynamics of long polymer chains is considered theoretically. It is shown that interactions give rise to an exponential increase of the reptation time, tau(rep) similar to exp[(n/n*)(2/3)], if polymer chains are long enough: n \textgreater n* similar to N-e(3), where N-e is the number of monomers per entanglement. Mie propose a novel dynamical mechanism of activated reptation implying that neighboring chains exchange conformations of their terminal fragments. It is shown that the exchange mechanism is compatible with the equilibrium polymer chain statistics and that it provides a bridge between the previous theories.
