Abstract: Photoinduced ATRP is a controlled radical polymerization in the presence of UV/visible light and can be used to synthesize functional polymer materials which can control the molecular structure. The polymerization kinetics was studied by changing illumination time, intensity and frequency of the light source. The amount of transition metal catalyst in photo-induced ATRP polymerization is reduced to less than 100 μg/g, which makes industrial application of controlled free radical technology possible. In this paper, the research progress of direct/indirect light-induced atom transfer radical polymerization (ATRP) is reviewed from the aspects of light source, catalyst, ligand and initiator.

摘要： 光诱导原子转移自由基聚合（ATRP）是在紫外/可见光照下实施的可控自由基聚合反应，可用于合成分子结构可控的功能性高分子材料。通过改变光照时间、强度和频率等因素来研究聚合反应动力学。光诱导ATRP反应中过渡金属催化剂质量分数实质性地降低至100 μg/g以下，使可控自由基技术的工业应用成为可能。从光源、催化剂、配体及引发剂等方面综述了直接/间接光诱导ATRP反应的研究现状。
