It relates to a kind of method, it includes being blended to prepare the polyimides of arylamine functionalization by polyimide resin and primary alkyl amine organic compound, and the arylamine degree of functionality of this polyimides is relative to any acid anhydride degree of functionality excess.The weight average molecular weight (Mw) of polyimide resin can be 5,000 to 100,000 dalton.Organic compound can include that at least one primary aliphatic amine does not have being directly connected to base and not having selected from following sense of nitrogen and aryl: halogen official can, hydroxyl-functional, sulfonic acid official can, sulfonate functional, and combinations thereof.The disclosure is directed to polyimides and the polyimides of aryl imide functionalization also with alkylamine functionalization, and the arylamine degree of functionality that they have is relative to any acid anhydride degree of functionality excess, and relates to the goods prepared by them. |
