It is shown that although Glauberrsquo;s timehyphen;dependent Ising model with a magnetic field cannot be solved in general, it can be solved in a hydrodynamic limit. This solution is useful for describing the relaxation kinetics of polymers, whose equilibrium properties are equivalent to a onehyphen;dimensional Ising model. The general properties of the hydrodynamic approach are discussed.
