摘要
用 3 ,3′ -4 ,4′ -二苯甲酮四羧酸二酐 (BTDA)分别与两种自制单体 :3 ,3′ ,5 ,5′ -四甲基 -4 ,4′ -二氨基二苯甲烷 (单体A)和 3 ,3′ ,5 ,5′ -四甲基 -4 ,4′-二氨基二苯甲酮 (单体B) ,经低温溶液缩聚 -高温化学亚胺化方法 ,合成了一系列可溶性光敏聚酰亚胺。采用WAXD、IR、UV、TMA、TGA等测试手段对树脂的结构与性能进行了表征和研究。该合成方法简便 ,分子量容易控制 ,产品纯度高 ,合成的光敏聚酰亚胺具有自增感性。
In this paper,an novel aromatic diamine monomer containing benzophenone moiety was synthesized.The synthesis and properties of a series of soluble photosensitive polyimides (PSPI) based on the aromatic diamine monomers and 3,3′,4,4′-benzophenonetetracarboxylic dianhydride (BTDA) were studied by means of WAXD,IR,UV, DSC,TGA,TMA and stress-strain analysis.This method is simple and the molecular weights of resins are easy control.The process of the PSPI photo-crosslinking reaction was monitored by IR method,and the apparent speed of the PSPI thermal decomposition reaction based on TGA was studied by the methods of derivative thermogravimetry (DTG).
