Abstract
Film forming aromatic organic polymers are provided having a dielectric constant greater than 3 resulting from the polymerization of aromatic organic monomers having orientable organic dipolar groups with a net dipole moment of at least 0.5 Debye. Among the aromatic organic polymers are included polyimides and polyetherimides having repeat main chain groups with orientable organic dipolar groups with non-symmetrically positioned polar radicals, such as fluoro and nitrile.
