PEEK(TM)-like Phthalonitriles: Melt-Processable, High-Temperature Polymers

The Naval Research Laboratory (NRL) has developed a new class of PEEKā„¢-like phthalonitrile (PN) resins for use in a variety of applications due to their ease of processability when in a melt-state followed by curing to produce high-temperature, high-char polymeric thermosets. The PN resins, where n < 1, were initially designed to fabricate polymer matrix composites (PMC) by cost effective manufacturing methods such as resin transfer molding, a type of out of autoclave (OOA) processing.
