Synthesis of an active substance for microcapsules in a polymer composite with a self-healing effect

Introduction. The aim of this study is to examine the properties of a synthesized epoxy resin hardener based on dicyclopentadiene and maleic anhydride. Materials and methods. The following chemical reagents were used for synthesis: dicyclopentadiene 98%, maleic anhydride (technical), trichloromethane (C.P.). The research was carried out with the Sintecor IR 10 FTIR spectrometer, the STA 449 F1 Jupiter thermogravimetric analyzer. Results and discussion. Studying the initial substances allowed the calculated and experimental data to be correlated. Subsequent operations then revealed the structure and thermal properties of the obtained adduct. Conclusion. As a result of this research, an epoxy resin hardener has been obtained that can withstand a wide range of temperature variations. The synthesized substance is expected to find practical application in self-healing polymer composites.
