Abstract:

Phthalonitrile thermoset polymers and Composites having flame resistance are formed by combining a phthalonitrile monomer in the melt stage with a halogen-containing aromatic amine curing agent. The halogen-containing aromatic amine curing agent is selected from the group consisting of aromatic amine curing agents having the general formula NH.-ArO,Ar1-X-Ar1-OAr1-NH2, wherein Ar1 and Ar2 are substituted or unsubstituteil aromatic groups, y is O or greater, and X is -CCF32- and aromatic amine curing agents having the general formula NH2-Ar1O, Ar-Z-Ar3-OAr1u-NH2 wherein Z is a connecting bond or a linking group other than, oxygen or CCF32- , u is O or greater and Ar3 and Ar2 are aromatic groups and wherein either Ar3 or Ar1 or both Ar3 and Ar1 are substituted with at least one halogen atom or halo-substituted alkyl group.
