中文摘要： 水溶性伯胺聚合物在纳米材料和生物医药等新兴领域已显现巨大的应用潜力。探索温和条件下伯胺聚合物的快捷可控合成新方法，必将促进相关领域的发展。本项目拟探讨伯胺单体离子缔合调控的可见光活化室温水溶液RAFT聚合特征，进而探索在室温水溶液中伯胺聚合物的快捷可控合成新方法。为达此目标，我们拟合成不同结构特征的甲基丙烯酰胺类伯胺单体；改变单体结构或反离子种类，调节单体浓度或水溶液温度，从而调控单体离子缔合状态；采用烷基磺酸或烷基苯磺酸等，诱导单体离子团簇化；通过间歇性光开关，实时启动或终止聚合；进而探讨伯胺单体离子缔合调控的可见光活化室温水溶液RAFT聚合和共聚合特征，实现聚合过程的间歇性光开关控制，快捷可控合成设定组成和共聚分布的水溶性伯胺聚合物。本项目的实施将加深对离子化单体水溶液聚合特性的理解，为快捷可控合成伯胺衍生功能聚合物提供新方法，充实并拓展我们前期创建的可见光活化室温RAFT聚合。

英文摘要： Thanks to the particularly fascinating properties, primary-amine-based water soluble polymers have been evidenced to have wide potential applications for fabricating nanomaterials and biomedical related functional materials. Exploring facile technique for the rapid and well-controlled synthesis of these water soluble polymers under mild conditions is essential to push forward such applications. To this end, the effect of monomer ion asociation on the visible light activated ambient aqueous RAFT polymerization of primary-amine-based monomers will be intensively studied, accordingly a new approach to the facile and rapid synthesis of well-defined primary-amine-based water soluble polymers under ambient aqueous conditions will be explored. To this end, the primary-amine-based water soluble methacrylamides with the targeted molecular structures will be synthesized. The monomer ion association will be modulated either by changing their molecular structures or counter-ions, or adjusting monomer concentration or solution temperature. The ion clusters of these monomers will be induced by complexing with alkyl sulfonic acid or alkylbenzene sulfonic acid etc. Moreover, this polymerization will be started up or ceased off periodically by turning on or off the visible light periodically in the duration of RAFT polymerizati
