将４－［对硝基苯基氧化偶氮苯基］甘油单醚与六亚甲基二异氰酸酯的缩二脲进行电场极化交联反应，合成交联型非线性光学聚合物，并用ＦＴ—ＩＲ光谱和ＤＳＣ对交联反应过程进行了详细研究。利用紫外可见吸收光谱对膜极化前后的取向以及在室温和升温下取向膜的稳定性进行了研究，并对极化膜的非线性光学系数ｄ３３进行了推算。
The polarization-crosslinking reaction of 4- [p-nitrophenyl azoxy phenyl] glycerol monoether and the biuret of hexamethylene diisocyanate was carried out to synthesize a cross-linked non-linear optical polymer and the FT- IR spectroscopy and DSC cross-linked reaction process was studied in detail. The orientation of the film before and after polarization and the stability of the oriented film at room temperature and temperature were investigated by UV-Vis absorption spectroscopy. The nonlinear optical coefficient d33 of the polarizing film was calculated.
