Abstract : Phthalonitrile resins useful, as high-temperature coatings and plastics and in high-temperature composites are obtained by heating a diphthalonitrile monomer with a primary amine from a temperature from about the melting point of the monomer to about the decomposition temperature of the resin. The resins can also be prepared by dissolving a diphthalonitrile monomer in a solvent, e.g. acetonitrile, adding a primary amine to form a suspension, heating the suspensions to the B-stage, quenching the suspension, removing the solvent, and heating the residue at a temperature from about its melting point to about the decomposition temperature of the resin.
