Abstract : A copolymer is formed from reacting, within a melt, a phthalonitrile resin with an epoxy resin having at least three epoxy groups. In an alternative embodiment, a copolymer is formed by reacting a phthalonitrile resin with an epoxy resin, at least one of the epoxy and phthalonitrile resins having a perfluorinated carbon. The copolymers of the present invention have exceptional thermal stability and a low affinity for water.
