Bisphthalonitrile monomers were cured neat, with nucleophilic and redox coreactants, or in combination with a monofunctional model compound. Dynamic mechanical measurements on the resulting polymers from −150°C to +300°C turn up several differences attributable to differences in network structure. Rheovibron results were supplemented with solvent extraction, DSC, vapor pressure osmometry, and infrared spectroscopy to characterize the state of cure.
