This invention relates to the field of organic chemistry, more particularly, to a method of obtaining modified phthalonitriles comprising organophosphorus fragments, binding agents based thereon, as well as products produced with the use thereof, and can be used in a variety of technical fields, for example, in aircraft and automobile manufacturing to produce polymer composite materials. The invention makes it possible to produce phthalonitrile monomers comprising organophosphorus fragments from out of simpler and cheaper reagents, and to obtain them as individual substances, which simplifies the process of synthesis, reduces the glass transition temperature of monomers and increases the thermal oxidation stability of hardened polymers. The phthalonitrile monomer modified with organophosphorus fragments is characterized with the following general formula:
wherein R is a radical selected from the group comprising aryl, alkyl, aryloxy or alkyloxy substituents; and X is a divalent aryl substituent selected from a group comprising phenylenes and naphthylenes. A method of obtaining the modified phthalonitrile monomer according to this invention, a binder, and a prepreg based on the same, are also disclosed.
