Abstract
We present an analytical theory of microphase separation in the melt of bottlebrush and comblike block copolymers in the strong segregation limit. The constructed phase diagram predicts morphologies and dimensions of the microsegregated domains as a function of molecular masses of both blocks, grafting densities and lengths of side chains in the comblike and bottlebrush blocks. The theoretical predictions are corroborated by experimental data.
