FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry and relates to monomer of formulas (I) or (II) for making polymer composite material (PCM) or prepregs for PCM;
a method for production thereof, compositions based thereon and a method for hardening said compositions. Method of producing monomer according to claim 1 is characterized by that in medium of aprotic polar solvent mixing corresponding hydroxyphenoxyphthalonitrile with organic amine in molar ratio from 1:1 to 1:1.2, followed by addition of 0.33 molar equivalents of phosphorus oxychloride, holding the reaction mixture and recovering the product. Binder compositions include a monomer according to 1, aromatic diamine or bisphenol, and can also contain monomers of general formula (III)
where X is selected from the group
where R is an unsubstituted benzene ring.
EFFECT: invention discloses novel monomers, an efficient method for production thereof, compositions based on said monomers and methods for their hardening, which enable to obtain polymer matrices with high modulus of elasticity.
