The four-phase triple coaxial cylindrical microdomain morphology in a linear tetrablock quarterpolymer, consisting of polystyrene (PS), polyisoprene (PI), poly(dimethylsiloxane) (PDMS) and poly(2-vinylpyridine) (P2VP) was discussed. The four phases were clearly distinguished by transmission electron microscopy (TEM) when the two-step selective staining was applied. The results showed that the PI, PDMS, and P2VP microphases formed triple coaxial cylinders with a hexagonal shape packed in a hexogonal array in the PS microphases, which formed the honeycomb shaped matrix.
