摘　　要：本文以溶液共混法制备了聚酰亚胺和聚醚砜的共混物,研究了该体系的红外光谱、热性能和耐碱性。实验结果表明:聚酰亚胺与聚醚砜形成部分互溶的半互穿网络(IPN)结构,聚醚砜可以改善聚酰亚胺的耐碱性。PI-PES blends were prepared from HCON (CH_3)_2 solvent, the IR spectra, thermal property and resistance to bases were investigated. The results show that the structure of PI-PES is in the form of interma- cromolecule polymer network (IPN), and that PES improves PI＇s alkali resistance, which is related to the contents of PES.
