We show that at a second-order phase transition, of -like system, a necessary condition for stretched exponential decay of the time-dependent structure factor is obeyed. Using the ideas presented in this proof, a crude estimate of the decay of the structure factor is obtained and shown to yield stretched exponential decay under very reasonable conditions.
