The results of theories of the Ostwald ripening and coalescence applied to molten quiescent polymer blends with dispersed phase structure were analyzed. From a comparison of predictions of the theories with available experimental results follows that coarsening of the phase structure in quiescent po
## Abstract The consequences of the interfacial mobility on the coalescence process in immiscible polymer blends was studied. Blends of PIB and PDMS with 10 vol.% PIB were subjected to shear‐flow step‐down experiments under controlled conditions. The blend was initially sheared at high shear rate t
