报道了甲基丙烯酸2-氨基乙酯（AEMA）的水相可逆加成-断裂链转移（RAFT）直接均聚和嵌段共聚反应。AEMA的受控“活性”聚合直接在水性缓冲液中使用4-氰基戊酸二硫代苯甲酸酯（CTP）作为链转移剂（CTA）和2，2 '-偶氮双（2-咪唑啉基丙烷）二盐酸盐（VA-044）作为引发剂在50 ℃下进行。聚合的受控“活性”特征用伪一级动力学曲线、分子量随转化率的线性增加和低多分散性（PDI）（
We report the direct homopolymerization and block copolymerization of 2-aminoethyl methacrylate (AEMA) via aqueous reversible addition-fragmentation chain transfer (RAFT) polymerization. The controlled "living" polymerization of AEMA was carried out directly in aqueous buffer using 4-cyanopentanoic acid dithiobenzoate (CTP) as the chain transfer agent (CTA), and 2,2'-azobis(2-imidazolinylpropane) dihydrochloride (VA-044) as the initiator at 50 degrees C. The controlled "living" character of the polymerization was verified with pseudo-first order kinetic plots, a linear increase of the molecular weight with conversion, and low polydispersities (PDIs) (
