Abstract: Polyimides derived from a primary aromatic diamine and aromatic dianhydride mono-mer moieties, wherein one or more of said moieties contain at least one substituent on the aromatic ring selected from propyl and butyl, especially from isopropyl, isobutyl, tert.butyl, show good solubility and are well suitable as dielectric material in electronic devices such as capacitors and organic field effect transistors.
