摘要
超支化聚酰亚胺(HBPIs)具有超支化聚合物和聚酰亚胺的综合性能,较高的玻璃化温度和良好的溶解性能。总结了用AB2型单体、A2+B3型单体和A2+B′B2型单体合成HBPIs的方法,并对其性能及应用进行了说明。AB2型单体难以合成,A2+B3型单体聚合虽然具有易制备和可以修饰结构的优点但容易产生凝胶化反应,用A2+B′B2型单体制备HBPIs可避免凝胶化反应,有利于实现HBPIs的大规模生产。
Hyperbranehed polyimides （HBPIs） possess the combination property of hyperbranched polymers and polyimides, with higher glass transition temperatures and superior solubility. The preparation processes of HBPIs synthesized from different types of monomers are reviewed, such as ABe, A2＋B3, and A2＋B＇Bemonomers, and the characteristics and application of HBPIs are discussed. In these methods, the synthesis of ABe monomers is difficult, and the polymerization of A2 q-B3 monomers is easy to prepare and can modify structure, but easily result in gelation, while the synthesis of hyperbranched polyimides from A2 ＋B＇B2 monomers can avoid gel formation and make it easy to prepare HBPIs in a large scale.
