popup.description1
The project is aimed at significantly expanding the possibilities of creating and using polymer composites with extreme properties by developing a universal platform for binders and a new approach to aromatic nitriles as building blocks for heat-resistant polymers that combine high working temperature, high mechanical strength, and resistance to thermo-oxidative destruction. Currently, Ukrainian researchers and material developers do not have reliable access to binders that provide the creation of polymer composites with a long-term heat resistance limit of 350-450 °C for the aerospace industry, energy, and communication systems. The research plan involves the development of protocols for the synthesis of aromatic tetranitriles, adapted for potential semi-industrial scaling. An economically feasible approach to the synthesis of oligomeric systems, doped with Si-B-P nanoclusters, will be developed. Also, a previously unknown mechanism of partial deactivation of reactive chains of thermo-oxidative destruction through up-conversion energy dissipation of migrating radicals will be studied. Based on the synthesized binders, samples of heat-resistant composites with fibrous and dispersed fillers will be obtained and their characteristics studied

This report presents the synthesis and modification of aromatic phthalonitrile-based monomers, oligomers, and polymers designed for high-temperature, high-performance composite materials. Scalable protocols were developed to produce monomers in multigram quantities. The studies were carried out aimed at assessing the effectiveness of the synthesis of aromatic tetranitriles and dinitriles based on the optimal power and polymerization availability of output blocks.
