Abstract Phthalontirile resins are renowned as the most heat‐resistant polymeric materials and exhibit exceptional performance under harsh conditions. Consequently, phthalonitrile thermosets offer potential to substitute metals in hot parts, thereby broadening operational limits of plastic high‐tech applications. Given their unique combination properties, phthalonitriles have garnered significant demand across sectors such aerospace, automotive, electronics, renewable energy. With industrial production application recently initiated several countries, questions regarding sustainability these naturally arisen. Thermosetting materials, owing highly cross‐linked architecture, cannot be recycled, necessitating adoption synthetic methods utilizing bio‐feedstock raw green protocols mitigate environmental impact. The present prospective review summarizes analyzes current state‐of‐the‐art bio‐based discusses directions for research development new areas, with a focus on challenge maintaining high‐performance levels during transition materials.
