US Classification:

205167

Abstract:

The surface modification of polyimide materials by a chemical process is disclosed to provide a variety of functional groups on the surface. The surface is treated to produce polyamic acid carboxyl groups which are subsequently reacted with epoxies, hydrazines, or alcohols. The carboxyl groups can be also be subjected to other organic reactions, such as reduction with metal hydrides and the like. The versatility and controllability of this process lends itself to promoting adhesion of the polyimide to similarly treated polyimides, other polymers and other substrates as well as combining with metals such as metal catalysts used for depositing conductors on non-conductive surfaces such as circuit boards.

International Classification:

C25D 502

US Classification:

204 15

Abstract:

Structures and methods of fabrication thereof wherein the method selectively supplies electrons to a first electroactive material in the presence of a second electroactive material wherein the first and second electroactive materials have different redox potentials. The electrons are selectively supplied either by electrochemical means or by appropriately chosen reducing agents. A structure fabricated by these methods has a first electroactive body disposed on a second electroactive body wherein the first body has a pattern therein exposing at the base thereof the surface of the second electroactive material body. Electrons can be selectively supplied to the surface of the second electroactive material body which is exposed at the base of the pattern in the first electroactive material body. Upon exposing the structure to a seeding solution seed is selectively supplied to those regions to which electrons have been selectively supplied. Electrically conductive material can then be electrolessly deposited onto the seed material to form an electrically conductive pattern in the pattern in the first electroactive body.

US Classification:

427 96

Abstract:

The disclosure describes a multilayer article of manufacture comprising a substrate having adhered to it a terminally unsaturated adhesive polyimide, where the surface of the adhesive opposite the substrate is adhered to a polyimide, the article further characterized in having one set or a plurality of alternating layers of the terminally unsaturated adhesive polyimide and the polyimide. In another embodiment, the article has at least one adhesive polyimide layer adhered to a metal substrate or an electrical circuit component such as an integrated circuit, or means for forming electrical connections in an electrical circuit such as metal conduits on the circuit or a wiring network embedded within a ceramic and/or polymer substrate. In manufacturing the article of manufacture, a surface treatment technique such as wet process or a plasma/optional silane coupling agent may be applied to either the substrate, adhesive polyimide film or polyimide film prior to the bonding operation. A novel adhesive polyimide is also described which is an adhesive polyimide such as ODPA-APB terminated with unsaturated heterocyclic monoamines such as azaadenines, aminobenzotriazoles, aminopurines or aminopyrazolopyrimidines and optionally anhydrides, aminoacetylenes, vinylamines or amino phosphines.

International Classification:

C08L 7706

US Classification:

525420

Abstract:

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.
