The dynamics of pressure-induced phase separation in N-isopropylacrylamide gels is investigated by the measurement of forward light scattering. A high hydrostatic pressure of 1030 atm which had been applied to the gel was suddenly decreased to atmospheric pressure at a constant temperature. Simultaneously, the time evolution of the intensity of forward-scattered light was measured. The scattered light constituted a speckle pattern, the intensity of which increased with time in accordance with the linearized theory of spinodal decomposition. In this experiment, the hydrostatic pressure acted as an external parameter which keeps the state of the gel in equilibrium in either a shruken phase or a swollen phase.
