    摘要: The disclosure relates to a process that includes blending a polyimide resin and a primary alky amine organic compound to produce an aryl amine functionalized polyimide, having aryl amine functionality in excess of any anhydride functionality. The polyimide resin can have a weight average molecular weight (Mw) from 5,000 to 100,000 daltons. The organic compound can include at least one primary aliphatic amine without a direct linkage of a nitrogen to an aryl group and without a functionality selected from a halogen functionality, a hydroxyl functionality, a sulfonic acid functionality, a sulfonic acid salt functionality, and combinations thereof. The disclosure also relates to alkyl imide functionalized polyimides also with aryl amine functionalized polyimides, having aryl amine functionality in excess of any anhydride functionality and articles produced therefrom.
