For low shear rate, the time of reaction is of the same or der of the mixing time so that the morphology of the blend is controlled by the transient equilibrium between coalescence and breakup, which tends to develop from an PP phase dispersed in the EVA matrix to the phase inversion.
However, as the morphology development is a transient equilibrium between coalescence and breakup, the time of reaction must be longer than the time of mixing in order to control the morphology development by the extent of the reaction and consequently in order to control the phase inversion by rheological aspects of the two phases.
