在过去的十年中，原子转移自由基聚合（ATRP）由于其合成具有预定分子量，明确的分子结构和各种功能的聚合物的卓越能力而受到了极大的关注。采用ATRP处理水性分散介质在经济上和环境上都具有吸引力，尽管这一过程具有挑战性。本文综述了近年来在水性分散介质中进行ATRP的研究进展。必须考虑在聚合过程中保持“受控/活性”特性以及胶体稳定性的相关问题。随着对ATRP机理的深入了解和新引发技术的发展，如电子转移活化剂（AGET）等，ATRP在水体系中的应用得到了极大的促进。综述了1998 - 2009年ATRP在分散介质中的主要研究进展，包括微乳液、微乳液、乳液、悬浮液和分散聚合。
During the last decade, atom transfer radical polymerization (ATRP) received significant attention due to its exceptional capability of synthesizing polymers with pre-determined molecular weight, well-defined molecular architectures and various functionalities. It is economically and environmentally attractive to adopt ATRP to aqueous dispersed media, although the process is challenging. This review summarizes recent developments of conducting ATRP in aqueous dispersed media. The issues related to retaining “controlled/living” character as well as colloidal stability during the polymerization have to be considered. Better understanding the ATRP mechanism and development of new initiation techniques, such as activators generated by electron transfer (AGET) significantly facilitated ATRP in aqueous systems. This review covers the most important progress of ATRP in dispersed media from 1998 to 2009, including miniemulsion, microemulsion, emulsion, suspension and dispersed polymerization.
