ABSTRACT:
The present invention provides polyimides and co-polyimides that are organosoluble. The polyimides and co-polyimides are prepared from an aromatic diamine having tert-butyl group, i.e., 1,4-bis(4-aminophenoxy)-2-tert-butyl-benzene, or its mixture with other diamines, and a mixture of dianhydrides that containing DSDA or 6FDA or other diether-dianhydrides.
