Abstract
The present disclosure provides a functionalized phthalonitrile monomer derived from a polyhydric phenol comprising at least one furan group or thiophene group and 4-nitrophthalonitrile. The functionalized phthalonitrile monomer may be used in various thermosetting compositions which can be cured to form thermoset polymers having excellent thermal and mechanical properties, such as high thermal stability, heat resistance, high char yield, and enhanced structural rigidity.
