Abstract : Phosphazene-containing amines having at least one amine or substituted amine moiety reactive with nitrite groups of the phthalonitrile monomers or oligomeric resins are useful curing agents for phthalonitriles. Typically, the phosphazene-containing amines useful as curing agents in the present invention have the formula: wherein each Of X(1-6) is a hydrogen, an unsubstituted amine group, or an amine group substituted with C1-C12 alkyl groups or aromatic groups, at least one of X(1-6) includes an amine group, and each of R'(1-6) is an alkyl, aromatic, or alkyl-substituted aromatic moiety, or a linear polymer of the phosphazene-based amine monomer. The curing agents enhance the speed of cure and also add flame retardancy to the cured polymers.
