pNitroaniline and 4amino4nitrobiphenyl were reacted separately with diglycidylbisphenol A to gain multihydroxyl oligomers. The two oligomers were crosslinked with ophthaloxyl dichloride and toluene2,4diisocyanate to produce corresponding crosslinking polymers. Poling and crosslinking were carried out at the same time. The crosslinking reactions were studied by FTIR. The orientation and stability of the crosslinked poled polymers were studied by UVVis spectra. The crosslinked polymers based on nitrobiphenyl amine unit exhibit lower original orientation degree, but better orientational stability at 80 ℃.
