The spatial organization of end‐functionalized diblock copolymers of styrene and isoprene revealed two separate levels of microphase separation: one between the two blocks forming the microdomain and another between the polar and non‐polar material. The association produced by the latter process has a pronounced effect on the dynamics as revealed in rheology and dielectric spectroscopy. The introduction of a polar group into the different chain‐ends has a dramatic effect on the phase behavior of the diblock copolymers and provides new ways of controlling their miscibility.
