摘要：
A novel polyimide wherein a tetracarboxylic dianhydride comprising 3,3',4,4'-biphenyltetracarboxylic dianhydride as the essential component is the starting tetracarboxylic dianhydride component, and an amine comprising between 0.5 and 30 mole percent of a diamine represented by the following general formula is the starting diamine component. (wherein A is a direct bond or a crosslinking group, and R1-R4 each represent a substituent). It is possible to obtain a polyimide, a polyimide film and a laminated body with an improved adhesion property and an improved moisture permeation rate, even without surface treatment, comprising, as the essential tetracarboxylic dianhydride, 3,3',4,4'-biphenyltetracarboxylic dianhydride which has conventionally only yielded polyimides with low adhesive strength.
摘要（中）：
一种新型的聚酰亚胺，其中包含3,3'，4,4'-联苯四羧酸二酐作为主要成分的四羧酸二酐是起始的四羧酸二酐组分，和含有0.5至30摩尔％的由以下通式表示的二胺的胺 是起始的二胺组分。 （其中A是直接键或交联基团，并且R 1 -R 4各自表示取代基）。 即使没有表面处理，也可以获得聚酰亚胺，聚酰亚胺膜和具有改进的粘附性和改善的透湿速率的层压体，其包含作为主要的四羧酸二酐的3,3'，4,4'- 联苯四羧酸二酐，其通常仅产生具有低粘合强度的聚酰亚胺。
