摘要：

The relation between rheological properties and phase-separated structures of polymer blend solutions is investigated by using the shear microscopy method to obtain insight into the mechanism of steady state formation under shear flow. The time dependence of viscosity and morphology is observed after a stepwise increase of shear rate. We have found that a large strain needs to burst the initial domains, the time of which is related to the relaxation time of the initial domains.
