We perform off-lattice Monte Carlo simulations for multiblock chains, (5A-5B)n, with n = 10, 20, 30, 40, 50, and 60, in implicit selective solvent, using a discontinuous square-well potential. We present selected thermodynamic and structural properties as a function of the reduced temperature, such as the reduced energy per segment, the reduced heat capacity, and the mean-squared radius of gyration. We observe that the collapse-driven self-assembled structure is not spherical above certain value of chain length, N, and develops a non-spherical globular structure with multiple cores.
