Abstract : Substituted and unsubstituted di-phthalonitrile monomers devoid of ether and/or phenoxy groups are solid at room temperature and which monomers are defined by the following general formula: where R is an aromatic tetravalent radical, thermoplastic prepolymers and thermosetting polymers which polymers are solid at room temperature and have a defined glass transition temperature if said polymers are cured at a temperature below a critical temperature or are devoid of a glass transition temperature if said polymers are postcured at a temperature exceeding said critical temperature.
