Polymers of a polyfunctional epoxy compound, N,N,N',N'-tetraglycidyl-1,3-propylene bis(p-aminobenzoate), formed by reaction of such epoxy compound with aromatic polyamines. The disclosed polymers are useful as structural resins, e.g., as advanced composite matrix resins.

Polymer from aromatic diamine and N,N,N',N'-tetraglycidyl-1,3-propylene

Curable compositions comprising epoxide prepolymers and polyaminobenzoates, alone, or combined with reinforcements, e.g., graphite fibers, and, optionally modified with second resins. The cured resin fiber matrix compositions exhibit high toughness combined with excellent hot/wet strength.
