摘　　要：以含偶氮苯的三硫酯作为RAFT试剂,将N,N-二甲基丙烯酰胺通过RAFT本体聚合制备了光敏性的端基含偶氮苯的聚(N,N-二甲基丙烯酰胺),并通过紫外光谱、傅里叶变换红外光谱、核磁共振氢谱、凝胶渗透色谱对PDMA-AZO聚合物的结构进行了表征。PDMA-AZO聚合物在水、乙醇、三氯甲烷中的光敏性研究表明,PDMA-AZO聚合物在以上三种溶液中都能够进行快速、可逆的光致顺反异构反应,80s达到光稳态。Azobenzene-terminated poly(N, N-dimethylacrylamide)(PDMA-AZO) photosensitive polymers were synthesized by RAFT bulk polymerization of N, N-dimethylacrylamide(DMA) using azobenzene-containing trithiocarbonate(CTAAZO) as RAFT reagent, and the structure of the as-synthesized polmers was characterized by ultraviolet spectroscopy(UV), Fourier transform infrared spectroscopy(FT-IR), proton nuclear magnetic resonance spectroscopy(1H NMR) and gel permeation chromatography(GPC). Photosensitivity results of PDMA-AZO polymers in water, ethanol and chloroform show that PDMAAZO polymers can carry out fast and reversible photoinduced cis-trans isomerization in the above three solutions, reaching photo stable state in 80 s.
