ABSTRACT:
A method for preparing poly(imide-amide)s comprising reacting carbon monoxide, an aromatic or heteroaromatic diamine, and an aromatic or heteroaromatic di(trifluoromethane sulfonate), in the presence of solvent and a catalyst One of the aromatic reactants has a nucleus including a phthalimide ring system. The catalyst is a compound of a metal selected from the group consisting of platinum, palladium and nickel.
