To improve the cyano reactivity, cyano-terminated PPENs were prepared by the end-capping reaction of PPEN-OL with CBN; benzonitrile terminated polys were also prepared by the polycondensation of excess 4,4'-oxydianiline with 1,2-dihydro-2-(4-carboxyphenyl)-4-[4-(4-carboxyphenoxyl)phenyl]-phthalazinone, followed by end-capping with CBA. The polymers synthesized exhibited good solubility in NMP, DMAc and DMF, and were crosslinked to afford phenyl-s-triazine-containing polymers under the similar conditions.
