Monoallyloxyimides, diallyloxyimides and polyallyloxyimides of general Formula I. <IMAGE> wherein: X is an integer from 1 to 4 inclusive; R<1>, R<2>, and R<3> are independantly selected from the group comprising hydrogen, alkyl, arylalkyl or halogen; and A is all or part of an aromatic alicyclic or mixed aromatic/acylclic ring system optionally substituted with one or more alkyl, alkoxy, alkylthio, aryl, heteroaryl, aryloxy, carboxy, alkylamino, dialkylamino, amino, nitro, cyano, halo or haloalkyl groups, can be used as co-reactants in thermosetting matrix resins. The reactive monomers, either alone or with other comonomers, can give rise to cured resin matrix materials with high thermal stability. Mixed with suitable bismaleimide monomers, they can be cured into useful composites having substantially improved thermal stabilities. |
