中文摘要：

以聚丙烯酸苯酯为主链,2,4-二硝基苯胺,对硝基苯胺为主要原料,成功制备了4种含偶氮基团的聚丙烯酸苯酯,分别为对硝基苯胺接枝聚丙烯酸苯酯、2,4-二硝基苯胺接枝聚丙烯酸苯酯、对硝基偶氮苯胺接枝聚丙烯酸苯酯、2,4-二硝基苯胺接枝聚丙烯酸苯酯.用紫外（UV-vis）、红外光谱（FT-IR）对产物的结构进行表征,并测定光电性能.结果表明2,4-二硝基偶氮苯胺接枝聚丙烯酸酯的电光系数和光电导率最大,分别为14.53 pm/V和53.32×10-16（S/m）.

英文摘要：

In this paper,four kinds of azo group-containing polyacrylic acid phenyl ester were successfully synthesized by polyacrylic acid phenyl ester grafted with 2,4-dinitroaniline or p-nitroaniline which were called nitroaniline grafted polyacrylic acid phenyl ester,2,4-dinitroaniline grafted polyacrylic acid phenethyl ester,nitro aniline grafted polyacrylic acid phenethyl ester,2,4-dinitroaniline grafted polyacrylic acid phenethyl ester respectively and characterized by＇ UV-vis and FT-IR,as well as electro-optic properties were measured.The results show that the electro-optic coefficient and optical conductivity of 2,4-dinitro aniline azo grafted polyacrylate were 14.53pm/V and 53.32 × 10-16 （S/m） respectively.
