The presented work is devoted to the synthesis of new modifiers containing low-viscosity oligoesters of epoxy (methyl)acrylate with a branched structure, determination of optimal conditions for their production and the creation of new modifiers for various purposes with high performance characteristics based on them, due to the reaction of the interaction of propantriol-, polyoxychloropropylenetriglycidyl esters (met)with acrylic acids, it is dedicated to the production of hybrid epoxy compounds and the study of their properties. The synthesis of oligoepoxymethacrylates by esterification of trialkyl triepoxide with methacrylic acid has been carried out. The influence of esterification conditions on the composition and yield of reaction products has been studied. It is shown that by varying the reaction conditions, the process can be directed towards preferentially obtaining mono-, di- and trimethacrylic oligoesters. Synthesized oligoesterepoxymethacrylates are used as a modifier of epoxy resin. Self-extinguishing compositions were obtained on the basis of epoxy resin ED-20 and synthesized oligoester epoxymeth acrylates. The materials obtained by curing these compositions with amine and anhydride hardeners are characterized by increased physico-mechanical, adhesive and thermophysical properties.
