✦ Synopsis

As part of an ongoing effort to develop processable, high-performance resins for aerospace applications, a phenylethynyl-terminated imide (PETI) oligomer designated LaRCMT PETI-1 was developed. This reactive oligomer has a number-average molecular weight of 6300 g/mol and a Tg of 218Β°C. Upon curing the reactive oligomer at 350Β°C for 1 h, a tough material with a Tg of 249Β°C was obtained. The properties of cured PETI-1 in the form of composites, adhesive specimens, thin films, and neat resin moldings are excellent. The synthesis, characterization, and mechanical properties of this polyimide are discussed.
