Epoxy oligomer ranks second among oligomers in terms of production in the world.Epoxy oligomer is known to be widely used as a binder in the manufacture of many target compounds.This is due to the fact that its indicators can be adjusted in the synthesis process.It is produced on an industrial scale under various brand names (ED -16, ED -20, ED -22, etc.) the resulting oligomer has positive aspects and many disadvantages.The disadvantages include following: low heat resistance and adhesion, the presence of certain types of free monomers in the system, etc.to eliminate these indicators, the epoxy oligomer was modified with organic compounds of another nature [1-6].The modification process was carried out by the method of joint poly-condensation in an alkaline medium.Modification in the synthesis process (chemical modification) is currently characterized by its importance.From literary research, it became clear that the method of chemical modification is of greater interest to researchers working in this field than physical modification.This is due to the fact that the performance indicators of epoxy oligomer-based compounds chemically modified by polycondensation are approximately 1.5-2.0times higher than those of epoxy oligomer-based compounds obtained by polycondensation [7-9].Epoxy oligomer of various brands is widely used all over the world (in the USA, Europe, Japan, China, Korea, etc.), its production is growing rapidly from year to year.Russia alone produces more than 100 thousand tons of epoxy oligomers of various brands per year.Since the molecular mass of epoxy oligomers differs from each other by the amount of epoxy groups in their composition, their aggregate state (solid, liquid and viscous fluid) also differs.The solid-state epoxy oligomer is mainly used in the preparation of powdered colors
