摘要:

选用2,2'-双三氟甲基-4,4'-联苯二胺(TFDB)与二苯醚四甲酸二酐(ODPA)作为聚合物的基本骨架进行缩聚反应生成聚酰胺酸,再经过化学亚胺化得到可溶性聚酰亚胺(PI)。 通过调节2-甲基吡啶在亚胺化试剂中的含量以达到控制酰亚胺化程度的目的,探讨不同亚胺化程度的PI胶的显影性能。 结果表明,当n(2-甲基吡啶):n(乙酸酐)=1:5时,所合成的光敏聚酰亚胺的显影性能最优。

Abstract:

Condensation polymerization of 2,2'-bis(trifluoromethyl)-4,4'-diamino biphenyl(TFDB) and 3,3',4,4'-tetracarboxydiphthalic ether dianhydride(ODPA) gives a soluble polyimide. The effect of the degree of chemical imidization on positive photosensitive polyimide performance was investigated by adjusting the content of α-picoline in the imidization reagent to control the extent of the imide. The results show that the photosensitive polyimide has the best developing performance when the mole ratio of α-picoline to acetic anhydride is 1 to 5 in the process of chemical imidization.
