N2 - Recently there have been a number of studies on the kinetics of phase separation of polymer blends in early stage spinodal decomposition (SD) and on self-assembling processes, dynamics, and pattern (morphology) in the later stage SD as a problem of non-equilibrium statistical mechanics of long chain molecules. Most of the experimental studies utilized time-resolved light scattering (LS) methods 1-5, and only a limited number of studies utilized time-resolved small-angle neutron scattering (SANS) and small-angle X-ray scattering (SAXS) methods. We investigated the time evolution of the interfacial structure using time-resolved SANS and LS on the same blend specimens. In this report we discuss general trends on the time-change of SANS profiles in detail and the result on the time-evolution of the composition difference between two coexisting domains in the later stage SD. Deuterated polybutadiene and protonated polyisoprene samples used in this study were synthesized by a living anionic polymerization.
