The time-resolved light scattering experiments have been conducted to investigate the kinetics of coarsening of phase separated immiscible polymer blends with/or without of added block copolymer. The blends studied were polystyrene/poly(methyl methacrylate) mixtures with diblock copolymer composed of the corresponding homopolymers. The time evolution of the peak position and the scattered intensity maximum have been compared with theoretically predicted values of exponents for distinct time scales of the phase separation at various annealing temperature.
