Abstract
Time-resolved small-angle neutron-scattering (SANS) studies of spinoda l decomposition in hydrogen-bonded blends of polystyrene and poly(buty lmethacrylate) reveal extremely slow kinetics of phase separation in t he vicinity of the critical point. The experimental data are interpret ed within the context of a mean-field model that predicts energetic ba rriers to extended composition fluctuations. The scenario bears a rese mblance to dynamic critical phenomena in Ising systems with coupling t o a set of mobile impurities.
