Further improvements in polymerized monomeric reactants are achieved by end capping the phenylethynyl-terminated imide with resin precursor agents such as 4-phenylethynyl phthatic anhydride (PEPA) or biphenyl dianhydride-based polyimides, which offer toughness and flexibility up to 569°E (316°C) in carbon fiber nanocomposites. 

The polyimide resin formulations were based on combining various amounts of 3,4 oxydianiline and 4,4-(l,3-phenylenedioxy)dianaline with 4,4 bisphenol A dianhydride and 3,3, 4,4 -benzopehnone tetracarboxylic dianhydride and terminated in 4-phenylethynyl phthalate anhydride.
