Process for making polyimide-polyamic ester copolymers |
| abstract |
A process for making polyimide-polyamic ester copolymer composition comprising reacting at least one diamine, a pyromellitic diacid diester compound; at least one other tetracarboxylic diacid diester compound and a selected phosphoramide in the presence of a base catalyst to form a polyimide-polyamic acid ester copolymer. |
