Block copolymers of polyimide and poly (phenylquinoxaline) have been synthesized. They are useful, particularly as dielectric layers in thin film multilayer structures. The most preferred embodiments are formed from polyimides which are those from pyromellitic dianhydride and oxydianiline. The most preferred poly (phenylquinoxaline) is a monofunctional oligomer, which yields the best microstructure.

Polyimide-poly(phenylquinoxaline) block copolymers
