FIELD: chemistry.
SUBSTANCE: disclosed is a novel ketimine based on 4,4'-dichlorobenzophenone and guanidine, which is characterised by the formula 
, as well as a method for production thereof, which involves reaction of guanidine carbonate (bicarbonate) with 4,4'-dichlorobenzophenone in ethanol at temperature of 70°C for 4 hours at pH=3 in molar ratio of guanidine to 4,4'-dichlorobenzophenone of 1:1. The synthesised ketimine can be used in polycondensation reactions during synthesis of polyheteroarylenes which are characterised by a combination of high heat resistance, high strength, good dielectric properties and chemical and radiation resistance.
EFFECT: use of the disclosed ketimine increases melt flow index.
