This review highlights recent advances in the micellization of synthetic graft copolymers and those based on natural precursors, particularly polysaccharides. Synthesis and characterization of a broad range of architectures are discussed, along with different micellization procedures and fundamental micellar characteristics, such as morphology and size. Micelle formation by synthetic graft copolymers in aqueous media is examined in detail for different architectures of nonionic, ionic, and temperature and pH stimuli-responsive “double hydrophilic” copolymers. In this context, the problems associated with unimolecular micelles and the correlations between molecular characteristics are further addressed. In addition to backbone and side chain molecular weights, grafting density and topology are the major parameters that directly influence graft copolymer micellization. A similar overview is provided for graft …
