This invention relates to novel curable compositions comprising (a) a first component comprising an aromatic polymer having a first preponderant repeat unit and (b) a second component comprising an acetylene, maleimide, or vinyl terminated poly(imide) or poly(isoimide) or precursor thereof, which second component is compatible with the first component, has 1 to 300 second preponderant repeat units which are different from the first preponderant repeat units of the first component, is substantially free of elemental sulfur and reactive divalent sulfur, and is present in an amount effective to substantially cure the composition. The compositions are useful as adhesives, coatings and matrix resins for fiber reinforced composites. They exhibit improved adhesion to various substrates, increased tensile strength and improved resistance to cracking. The invention also relates to the composition which contains a reinforcing filler. The invention also relates to the composition after it has been cured. The invention further 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.

A curable composition comprising (a) a first component comprising an aromatic polymer having a first preponderant repeat unit selected from the group consisting of (i) poly(sulfone), (ii) poly(aryl ether ketone), (iii) poly(carbonate), (iv) poly(arylate), (v) poly(imide), (vi) poly(benzimidozopyrolo

A curable composition comprising (a) a first component comprising an aromatic polymer having a first preponderant repeat unit selected from the group consisting of (i) poly(sulfone), (ii) poly(aryl ether ketone), (iii) poly(carbonate), (iv) poly(arylate), (v) poly(imide), (vi) poly(benzimidozopyrolone, and (vii) poly(imide isoindoquinazolinedione), said aromatic polymer being substantially free of acetylene, maleimide, or vinyl terminal groups, and (b) a second component comprising an acetylene, maleimide, or vinyl terminated poly(imide) or poly(isomide) or precursor thereof, which second component is compatible with the first component, has 1 to 300 second preponderant repeat units which are different from the first preponderant repeat units, is substantially free of elemental sulfur and reactive divalent sulfur, and is present in an amount effective to substantially cure the composition to a gel content of at least about 10%, as measured by percent insolubles in chloroform.
