Dendrimer–like hyperbranched polymers (DBP)s have recently appeared as a new class of hyperbranched polymers. Although (DBP)s resemble dendrimers in branched architecture, they are composed of polymer chains between junctions and, accordingly, much higher in molecular weight and much larger in molecular size than dendrimers. Because of their specific hyperbranched structures and nano–size globular molecular shapes, (DBP)s have attracted much attention due to specialty functional materials and supra–structured nano–materials with many potential applications. In this review article, precise syntheses of DBP by previously reported procedures and recently developed new methodology based on “arm–first” divergent approach are highlighted. Furthermore, the possible synthesis of various (DBP)s having different branched architectures and polymer chains are introduced. Finally, their solution properties, sizes, and shapes are discussed.
