摘要：

The self-organization processes in a system of multiblock AB-copolymers with various chain and block lengths were studied using the method of integral equation theory for liquids in the PRISM approximation. The intramolecular conformation structure of the copolymers was calculated by the Monte Carlo method. The spinodal curves were determined and the character (micro versus macro) of the phase separation was studied depending on the system density and block size. In the region of microphase separation, the characteristic period of the structure is a nonmonotonic function of the block length and exhibits a minimum the position of which is independent of the total copolymer chain length.
