FIELD: chemistry.
SUBSTANCE: invention refers to method of producing heat-resistant heterocyclic polymers to be used as binding agents for heat-resistant black-reinforced, glass-reinforced and organoplastics, as a base for glues, sealants, caulking compounds, paint films. Aromatic bis-o-cyanamine reacts with 4,4'-(m-phenylendioxy)diphthalonitrile at temperature 160±2°C. 4,4'-(m-phenylendioxy)diphthalonitrile is introduced by cycles. Bis-o-cyanamine is 1,3-bis(3-cyano-4-aminophenoxy)benzene, or 3,3'-dicyano-4,4'-diaminodiphenylmethane, or 3,3'-dicyano-4,4'-diaminodiphenyloxide.
EFFECT: invention allows developing economical method of producing heat-resistant heterocyclic polymers, reducing possibility of collateral reactions, improving physical-mechanical properties of polymers.
