Abstract:

Two kinds of novel phenylethynyl terminated imide oligomers were prepared with BABB, APBP and PEPA. The melt viscosity stability of the oligomers and thermal stability, mechanical properties of cured resins were studied in this paper. The results show that the oligomers can be used to prepare the high perfor-mance resin-based composite materials via resin transfer molding(RTM) due to their low melt viscosities(about 1 Pa·s) and excellent stability at 200 ℃. The cured resins exhibit excellent thermal stability and mechanical properties.

Key words: Polyimide; Oligomer; Phenylethynyl-terminated
