Abstract

Abstract This invention relates to novel compositions of a poly(imide) having phenylindane diamine and/or dianhydride moieties in the poly(imide) backbone and a polymeric component comprising: (a) a poly(etherimide) free of phenyl indane moieties in its backbone; (b) a poly(sulfone); (c) a poly(aryl ether ketone); (d) a poly(carbonate); or (e) a poly(arylate); and the compositions which have been cured. The compositions are useful as adhesives, coatings and matrix resins for fiber reinforced composites. The invention also relates to a multi-layered article for use in electronic devices, the article comprising a plurality of layers each comprising a cured composition of the invention with one or more intervening layers of conductive or semi-conductive material.
