Abstract
Following the extensive works on dendrimers which are structurally perfect but tedious to prepare, the need for the development of structurally imperfect hyperbranched (hb) polymers has gained momentum. A dendrimer is constituted of terminal units (at the globular surface) and dendritic units (inside the macromolecular framework). Whereas a hb polymer is constituted of terminal units (at the irregular surface), linear units and dendritic units (both of which are distributed randomly inside the macromolecular framework). These structural variations in dendrimers and hb polymers arise from the difference in synthesis strategies and mechanism of their formation
