FIELD: chemistry. n SUBSTANCE: phthalonitrile monomer of the general formula n , n where R is selected from aryl, alkyl, aryloxy, or alkyloxy; X is selected from phenylene or naphthylene prepared by reacting, at least, one hydroxyl-containing phthalonitrile and a phosphorus-containing material selected from the group consisting of alkyl- or arylphosphoric acid, alkyl- or arylphosphorus acid, alkyl- or aryl-phosphorus acid, dichlorohydrin alkyl - or arylphosphine acid and dichlorohydrin alkyl- or arylphosphonate acid, followed by extracting the reaction interaction of the target product from the products, in the form of a modified organophosphorus fragments of the phthalonitrile monomer. A binder that is characterized by including the above-mentioned phthalonitrile monomer and aromatic diamine as a polymerisation initiator. The prepreg is made of the said binder and a reinforcing element. n EFFECT: new efficient method of producing new modified phthalonitrile monomers, a binder, and a prepreg on its basis is proposed. n 12 cl, 2 tbl, 1 dwg, 9 ex |
