The kinetics of spinodal decomposition has been studied by a Monte Carlo renormalization-group method. Using the standard blocking transformation, we numerically renormalize the evolving configurations during phase separation of a two-dimensional kinetic Ising ferromagnet with spin-exchange dynamics. We find that, as the scaling regime is approached, the domain size R grows in time t as R_tn, where we obtain n=0.338±0.008. This is consistent with the classical result of Lifshitz and Slyozov for Ostwald ripening, namely n=1/3
