摘要
综述了采用AB_2型单体、A_2+B_3型单体、A_2+B′B_2型单体和AB+AB_2型单体合成超支化聚酰亚胺(HBPI)的制备方法,重点介绍了A_2+B_3型单体(包括二酐/三胺、二胺/三酐单体)制备HBPI的技术、HBPI的改性及应用领域和发展前景。HBPI具有较高的玻璃化转变温度和良好的溶解性能。
This paper reviewed the preparation processes of hyperbranched polyimide (HBPI) synthesized from different types of monomers, such as AB2, A2+B3, A2+B'B2 and AB+AB2 monomers. The technologies for preparing HBPI from A2+B3 monomero (including di-anhydride/tri-amine and di-amine/tri-anhydride monomers), the modification, application field and development prospect of HBPI were emphatically introduced. HBPI possesses higher glass transition temperature and superior solubility.
