Abstract
Fluorinated phthalonitrile monomers exhibit low activity in polymerization initiated by a wide range of curing agents of various nature. On the contrary, the use of fluorinated diamines as hardeners for common non-fluorinated phthalonitrile monomer allows one to obtain thermosets with high glass transition temperature (Tg > 426 °C) and improved thermal oxidation stability (T5% = 520 °C in air).
