Rheology and Morphology of Dispersed Two-Phase Polymer Blends in Capillary Flow
In recent years there has been a great deal of interest in the studies of the structure and properties of polymer mixtures. However, there is little information in the literature concerning the morphologyrheology relationship and the principles which govern the morphology developments for the dispersed two-phase polymer blends in the molten state under continuous shear flow1-5. In previous papers6-7 a blending law based on model morphologies proposed earlier by Vinogradow8,9 was derived in order to evaluate the morphology of dispersed two-phase polymer blends during capillary flow. The purpose of the present study is to elucidate the morphology in the molten state of polymer mixtures under shear flow conditions.
