Effects of uniaxial compression on the spinodal decomposition (SD) process of a binary mixture of poly(styrene-ran-butadiene) (SBR) and polybutadiene (PB) were studied by using time-resolved light scattering. A given uniaxial compression was imposed

The unmixing process via spinodal decomposition of poly(styrene‐ran‐butadiene) (SBR)/polyisoprene (PI) mixtures was investigated by the time‐resolved light‐scattering method to see how it is affected by the temperature of phase separation T a

Spinodal decomposition of off‐critical mixtures of poly(styrene–random–butadiene) copolymer with polyisoprene or polybutadiene was investigated as a function of the composition w of the mixtures and of the phase separation temperature T by time

Mesh and strut microdomain structures were observed in a poly(styrene-b-butadiene)/polystyrene mixture. The mesh structure consists of alternating parallel sheets composed of A and B macromolecules in which one type of sheets (e.g. A) is fused by cat

The later‐stage spinodal decomposition (SD) of polymer mixtures at deep quenches were investigated by time‐resolved light scattering. The scaled structure factor F(x)≡qm (t,T)3I(x) with x≡q/qm (t,T) was analyzed as a function of time t or red
