Investigation of Phase Separation in a Partially Miscible Polymer Blend by Rheology

摘要: The phase boundary and phase‐separation dynamics of a binary poly(styrene‐co‐maleic anhydride)/poly(methyl methacrylate) blend have been investigated by rheological measurements light scattering. diagram was experimentally established rheology, in which the binodal line obtained dynamic temperature ramps spinodal temperatures were quantitatively estimated on basis theory developed Ajji et al. from viewpoints further diagram. Rheological can sensitively detect rather early stages separation compared with scattering techniques. It found that storage modulus initially increases over time subsequently decreases during nucleation growth; other hand, it always decreased decomposition. Compared techniques, to be relatively r...
