摘　　要：分别以4,4'-二胺基二苯醚(ODA)/3,3',4,4'-二苯醚四羧酸二酐(ODPA)和4,4'-双酚A二苯醚二胺(BAPP)/3,3',4,4'-二苯酮四羧酸二酐(BTDA)为原料,以溶液聚合形式合成了两种带有端胺基、重均相对分子质量在7000左右的聚酰亚胺齐聚物,并用红外光谱法对两种齐聚物的结构进行了表征。结果表明,这两种齐聚物均能完全溶于双马来酰亚胺(BMI)树脂的共聚单体(烯丙基双酚A)中,可用于BMI的增韧。Two kinds of polyimide oligmers with amine end group were synthesized with ODA/ODPA and BAPP/BTDA respectively. The structure of the polyimide oligmers were characterized by FT-IR spectra. The weight average molecular weights of the oligmers were around 7000.Both of the two oligmers can dissolved in RS that can react with BMI.
