The melting order of polymer blend components influences the morphology development during extrusion. An inversion in phase continuity occurs during processing if the minor component softens first. Additional power input is required to process the blend due to this inversion. The power input is intensified and the inversion is delayed when a reaction occurs during blending. Increasing the concentration of the minor phase or decreasing the mixer shear rate delays the inversion.
