There have been many studies to control the size and morphology of the self-assembled structure of polymer. Discrete polymer, which has precisely defined molecular weight, molecular weight distribution, and sequence, has been of great interest in that it can control the nanostructures due to its specifically defined chemical and physical properties. Crystallization Driven Self-Assembly (CDSA) is one of the promising area which can control the conformation of self-assembled structure, as the core-forming block requires a precise control. In this study, PLLA with a branched PEG was polymerized to investigate the morphological change in their self-assembly structure. Without the molecular weight distribution, the effect of repeating unit on the morphological change was clearly studied.
