摘要
以6-(4'-甲氧基-4-氧基偶氮苯)甲基丙烯酸乙酯(Azo MA)为单体,三硫代碳酸酯(DMP)为RAFT试剂,偶氮二异丁腈(AIBN)为引发剂,采用可逆加成-裂解链转移聚合法制备了偶氮苯聚合物(PAzo MA),其结构和性能经1H NMR,FT-IR,GPC和UV-Vis表征。结果表明:PAzo MA结构规整,分子量分布较窄(1.25),在光照下可发生构型反转。
A azobenzene polymer（PAzoMA） was prepared by reversible addition fragmentation chain transfer （ RAFT ） polymerization, using 6- （ 4＇-methoxy-4-oxy-azobenzene ） hexyl methacrylate （ Azo- MA） as monomer, DMP as RAFT agent and AIBN as initiator. The structure and performance were characterized by 1H NMR, FT-IR, GPC and UV-Vis. The results showed that PAzoMA was in regular structure and narrow molecular weight distribution （ 1.25 ）. The configuration of PAzoMA transformed under illumination.
