摘要：
The structure development of the late stage of the spinodal decomposition of a binary polymer blend under shear flow has been studied by simultaneous measurement of rheological functions and the 2-dimensional light scattering pattern obtained by small angle light scattering (SALS). During the structure development at constant shear rate the viscosity passes through maxima which are related to the onset of the structure deformation. In a creep recovery experiment an unusual reversal of the recovery is observed which is related to the relaxation of the anisotropic non-equilibrium morphology.
