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

The Naval Research Laboratory (NRL) has developed a new class of PEEK™-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.

PEEK(TM)-like Phthalonitriles: Base Resin Manufacturing

The Naval Research Laboratory (NRL) has developed a new class of PEEK™-like phthalonitrile (PN) resins, when in the melt-state, are easily processed and cured, and produce high-temperature thermosets. The PN base resins are synthesized in a two-step, one-pot reaction in quantitative yields and require no further purification (n
