In this work, the synthesis and the scheme for obtaining an oligomer based on
epiiodhydrin with diphenylguanidine were studied, the proportions of epiiodhydrin in the initial
mixture, the yield of oligomers, and the reduced viscosity were studied. The results of spectroscopic
and elemental analyzes are obtained, which show that changes in the ratio of monomers have almost
no effect on the iodine content in the oligomer. This is apparently due to the fact that epiiodhydrin is
much more active in reactions than amino compounds. By studying the degree of conversion on the
viscosity of the oligomerization products, the effects on the intrinsic viscosity of the oligomer were
determined. The use of epiiodhydrin is due to its high reactivity due to the activity of the epoxy group
and the mobility of the iodine atom of the iodomethyl group. In addition, based on a study of literary
sources, we found that most of the substances intended to stabilize and slow down the combustion of
polymer compositions contain ionically or covalently bound iodine, which gives them such valuable
specific properties. The properties of surfactants are formed in the process of their synthesis, since
the mechanism and patterns of synthesis are interrelated with the properties of the compounds. We
have studied the interaction of epiiodhydrin with diphenylguanidine and found that spontaneous
oligomerization occurs at a sufficient rate in bulk at room temperature. Spontaneous polymerization
of epiiodhydrin with diphenylguanidine was studied by the dilatometric method, and the contraction
coefficient, which determines the degree of change in the volume of the monomer mixture, was also
studied. The mechanism of synthesis, the structure of the final product, technological and kinetic
regularities of the process make it possible to predict the physical and colloid-chemical properties of
oligomers. Determining the properties of products in conjunction with mathematical modeling of
synthesis is the subject of further research.
