摘要： A method of isomerizing an isoimide to an n-imide is described wherein an electron is supplied to the isoimide which induces the isomerization and wherein the isomerization is catalytic to the electron which remains available to initiate further isomerization. A polyimide is deposited onto a conductive substrate by providing a composition containing a polyisoimide and an electrolyte providing the substrate and a counter electrode in the composition, and providing a bias between the substrate and counter electrode to thereby supply an electron to the polyisoimide which isomerizes to deposit the insoluble polyimide on the substrate.

摘要： The invention relates to the formation of isoimides from amic acids, especially polyisoimides by a novel process in which polyimides are first converted to polyamic acids and then contacted with an isoimidizing agent. An acyl halide of a heterocyclic nitrogen compound or an acyl halide of a heterocyclic sulphur compound can be used as the isoimidizing agent. The isoimidization may also be carried out in the presence of a compound containing a heterocyclic nitrogen especially a solvent containing a heterocyclic nitrogen.The invention is especially applicable to conducting nucleophilic addition reactions on the surface of polyimides where the surface has been converted to a polyamic acid or on the surface of polyamic acid materials followed by isoimidization and reaction of the isoimide with a nucleophile such as an amine or organic hydroxy compound.Photosensitive metal compounds or electroless metal coating catalysts can be coordinated with the compositions obtained.
