Hyperbranched polymers (HBPs) have been studied for over three decades now; yet several interesting aspects continue to draw the attention of researchers worldwide. This is because of the simplicity of synthesis, their unique globular structure, and the numerous peripherally located functional groups that can be utilised to impart a variety of attributes, such as core-shell amphiphilicity, amphiphilicity, clickable polymeric scaffolds, multifunctional crosslinkers, Several reviews have been written on HBPs with a focus on synthetic strategies, structural diversity, and their potential applications; in this short feature article, we have taken an alternate approach to highlight some of the unique structural features of HBPs and their influence on the properties of HBPs. We also discuss their versatility and adaptability for the generation of several interesting functional polymeric systems. In the latter half, we focus on the utilisation of HBPs as multifunctional scaffolds, that rely on the numerous peripheral terminal groups. We conclude by drawing a structuro-functional analogy between the range of peripherally functionalised HBPs and other analogous, but more complex, polymeric systems. We believe that this review will serve as a visual sounding board that would encourage the development of several other applications for this class of unique polymers.
超支化聚合物（HBPs）至今已被研究了三十多年；然而，几个有趣的方面仍继续吸引着全球研究人员的关注。这是由于其合成的简便性、独特的球状结构以及众多位于外围的官能团，这些官能团可用于赋予各种特性，如核壳两亲性、两亲性、可点击的聚合物支架、多功能交联剂。关于超支化聚合物已经有几篇综述，重点关注合成策略、结构多样性及其潜在应用；在这篇简短的专题文章中，我们采用了另一种方法来突出超支化聚合物的一些独特结构特征及其对超支化聚合物性能的影响。我们还讨论了它们在生成几种有趣的功能性聚合物体系方面的多功能性和适应性。在后半部分，我们重点关注超支化聚合物作为多功能支架的应用，这依赖于众多的外围末端基团。我们通过在一系列外围功能化化的超支化聚合物与其他类似但更复杂的聚合物体系之间进行结构 - 功能类比来得出结论。我们相信，这篇综述将作为一个直观的交流平台，鼓励为这类独特的聚合物开发其他多种应用。
