超支化聚酯的合成及应用

Synthesis and application of hyperbranched polyester

超支化聚酯具有高度支化体系,对称的球型三维结构,且分子链之间不易发生缠绕,黏度低,在溶解性方面也表现出较好的优点。还具有合成方法简单、原料价格相对低廉的优点,所以在应用方面表现出很大的优势。其在高分子共混改性、涂料合成与改性、环氧树脂改性以及高分子膜材料中的应用非常广泛。主要综述了脂肪族和芳香族超支化聚酯的合成以及应用方面的研究。

The hyperbranched polyesters have highly branched system,symmetric spherical 3D structure and molecular chain is not easy to occur winding,Low viscosity,but also have the advantages of solubility.The hyperbranched polyesters are easy to synthesis,and raw material are low prices,so its show great advantages in application.Especially the material are widely used in the aspect of blending modification with polymer materials, synthesis and modification of coatings,modification of epoxy resin,and polymer membrane materials.The synthesis and application of aliphatic and aromatic hyperbranched polyesters were reviewed.
