摘　　要：通过溶液聚合方法合成了含对二乙烯基偶氮苯(DVAB)和对二甲基丙烯酰胺偶氮苯(BMAAB)两种功能单体的可溶性共聚物。在合成聚合物时,单体固含量为7g/100mL乙醇,偶氮功能单体的含量为MAA、MMA总量的2%(质量)时,能得到可溶性聚合物。用UV、FT-IR、13C-NMR等现代分析方法表征了聚合物的结构,含DVAB的聚合物其最大紫外吸收波长为342nm,较DVAB的最大紫外吸收波长(357nm)短。而含BMAAB聚合物的最大吸收波长,在反应前后未发生变化。Azopolymers can be used as a new type colonic-specific drug release carriers what have some characteristic of enzyme-controlled and accurate garget. Azopolymers were synthesised with MAA, MMA, DVAB/BMAAB monomers by radical polymerization in ethanol solution. Conditions of polymerization were studied. The results show that when mass of MAA and MMA is 7 g in 100 mL ethanol, percent of azo functional monmers mass is 2% relation to total mass of MAA and MMA , copolymers can dissolve in ethanol. The structure of these azopolymers were also measured by UV, FT-IR, and()^( 13)C-NRM, λ__(max) of azopolymers of containing DVAB in UV is 342 nm shorter than λ_(max) 357 nm of DVAB. λ_(max) of azopolymers of containing BMAAB in UV does not change comparing with λ_(max) of BMAAB.
