We report the first numeric experiments on the thermodynamic relaxation in living polymers (polymers that can break and recombine reversibly) whose molecular weight distribution (MWD) is perturbed from equilibrium by a T-jump and then allowed to relax. In the simulation we use a modification of the Bond Fluctuation Method which is known to reproduce the correct Rouse dynamics of polymer chains. Our results indicate an excellent agreement with the predictions of a recently suggested theory [1, 2] of relaxation in living polymer systems.
