Morphology of AB0CB1D pentablock quadpolymers in melt is studied by Monte Carlo simulation, where B0 and B1 are the same polymer component. When the volume fractions of the two end‐blocks, φA, φD, and that of mid‐block, φC are all small, the B‐domain forms matrix phase, whereas the A‐, C‐, and D‐chains stay as cylindrical domains. A tetragonally packed cylindrical structure is observed in the composition range of 0.125 ≤ φC ≤ 0.188 at φA = φD = 0.125 and γ = 1.0, wherein γ is the volume fraction ratio of two B‐chains, that is, γ = φB0/φB1, defined as a symmetric factor. Another complex but periodic cylindrical structure is found at φA = φD = 0.125 and φC = 0.188 with quite wider γ range of 0.38 ≤ γ ≤ 0.64. By connecting D‐domains, this structure can be classified as the 3.3.4.3.4 Archimedean tiling, which is composed of imaginary regular triangles and squares. It should be noted that γ range of 3.3.4.3.4 phase is much wider for the present AB0CB1D pentablock quadpolymers than that for the AB0CB1 tetrablock terpolymers. In addition, the A‐domains have been found to display the periodic Cairo pentagonal tiling by drawing auxiliary connect lines.
