The properties of a polymer prepared from an aromatic diether-linked phthalonitrile resin, 4,4'-bis (3,4-dicyanophenoxy)biphenyl, and cured with 1,3-bis(3-amino phenoxy)benzene are reported. The resin is easily processed from the melt of the monomer in a controlled manner as a function of the amine content and processing conditions. The resulting polymers show an excellent retention of mechanical properties following inert atmosphere post-cure to 375°C and oxidative ageing at 315°C for 100 h. Results are reported for the effects of cure, post-cure and ageing conditions on the tensile and fracture properties of these polymers.
