摘　　要：以联苯四酸二酐(BPDA)和烯丙基胺为反应物,合成了N,N’-二烯丙基联苯双酰亚胺,该化合物在氯铂酸催化作用下与1,1,3,3-四甲基二硅氧烷通过硅氢加成反应合成了一种新型含硅聚酰亚胺(PI)。研究表明:含硅链段的引入有助于提高聚酰亚胺材料的溶解性能和熔融加工性能。各步产物通过红外光谱(FT-IR)与核磁共振(1 H-NMR)进行了结构表征,并通过热重分析仪(TGA)、示差扫描热分析仪(DSC)和尺寸排除色谱仪(SEC)对目标产物的热性能和分子量进行了测定研究。N, N ＇-diallyl biphenylbisimide was prepared by reacting 4,4 ＇-biphenyltetracarboxylic dianhydride （BP- DA） with allyl amine via imidization. Under the catalysis of ehloroplatinic acid, the polymerization via hydrosilylation was in itiated between N, N＇-dialiyl biphenylbisimide and 1, 1,3,3-tetramethytdisiloxane to offer the target siloxane-containing polyimide. The introduction of siloxane segment to polyimide backbone was found to be effective to improve the solubility and melt processability of polyimide, The products were structurally characterized by FT-IR and 1 H-NMR techniques. The thermal property and molecular weight of target polyimide were studied by thermogravimetrie analysis（TGA）, differential scanning calorimetry（DSC）and size exclusion chromatography（SEC）, respectively.
