The in situ reaction of a hydroxy group with a phthalonitrile system was carried out by the simple nucleophilic displacement of a nitro-substituent from 4-nitrophthalonitrile in a dipolar aprotic solvent, in a one-pot reaction. The hydroxy-containing phth

A new monomer containing thermosetting groups of two types, namely, propargyl ether and phthalonitrile, in the structure of the molecule was synthesized and studied. It was found that thermal polymerization was accompanied by the degradation of the monomer with propargyl ether decomposition. This problem can be solved using catalysts based on Cu(i) favoring the polymerization at both the propargyl group and phthalonitrile fragments. The cured monomer has a non-porous structure and high thermal properties (Vicat softening temperature 395 °C, T5% 451 °C). The low viscosity of the melt (a mold.
