摘　　要：利用4-(4-硝基苯偶氮)-1-萘酚的丙烯酸酯与短梗霉多糖进行接枝共聚,制备了侧基含偶氮苯生色团的短梗霉多糖聚合物,并用红外光谱、扫描电镜、X射线衍射、热重分析等手段对聚合物进行了表征.用紫外光谱研究了聚合物的光致变色性,结果表明聚合物具有良好的热稳定性和光致变色性.A photochromic polymer was prepared by grafting azobenzene groups 4-（4-nitro phenylazo）- 1-naphthol onto pullulan. FTIR, SEM, TGA and XRD were used to characterize the polymer samples. UV-Vis spectrum was used to test the photochromism properties of the product. The results showed that photoisomerization hapended between the trans and c/s isomers.
