超支化聚合物

超支化聚合物具有高度支化的三维球状结构及众多端基从而表现出与线型分子截然不同的性质，如无链缠结、低粘度和良好的相容性，且其合成方法简单，成本低，因此其在聚合物共混改性剂、涂料、药物缓释和催化反应等方面得到了广泛应用。综述了超支化聚合物的结构与性能及合成方法等方面，并简要介绍了其应用前景。

Hyperbranched Polymers

Hyperbranched polymers are a type of dendrimers that constitute a novel class of highly branched polymers with a Abstract large number of end groups. Because of their highly branched three-dimensional and sphere-like molecular architecture, hyperbranched polymers show very different properties from those of linear polymers, such as no inter chain entangling, low viscosity and high solubility, and the synthetic method is easy and the cost is low. They are mainly applied in polymer blending modifier, coating, medicine slow releasing agent, catalytic reaction, etc. In this article, the unique structural characteristics, properties and synthetic methods of hyperbranched polymers are reviewed. The application fields of hyperbranched polymers are also introduced.
