Abstract
In the limit of weak segregation, microphase separation in melts of symmetric multiblock copolymers with the structural formula A(mN/2)(B(N/2)A(N/2))(n)B-mN/2 was theoretically analyzed. It was shown for the first time that, in the case of these two-length-scale block copolymers AB, competition between ordering processes on different scales may lead to the formation of morphologies of cubic symmetry, instead of lamellar morphologies, as well as to abrupt changes in the scale of crystalline superstructures upon small variations in the block copolymer architecture. Phase diagrams in the space of system parameters were constructed.
