Abstract:
1. An adhesive composition comprising a mixture of: a maleimide terminated polyimide resin; a styrene-containing thermoplastic resin compatible with the maleimide terminated polyimide resin; optionally, a silane coupling agent; optionally, an ethylenically unsaturated compound with acid functionality; a thermally activated free radical curing agent; and at least one of an electrically conductive scrim, carbon fibers, electrically conductive particles, or combinations thereof, wherein the maleimide terminated polyimide resin comprises a reaction product of a primary aliphatic diamine having ten or more carbon atoms with a tetracarboxylic dianhydride followed by reaction with maleic anhydride, and wherein the styrene-containing thermoplastic resin and the maleimide terminated polyimide resin are both soluble together in an aromatic solvent.
