摘　　要：原子转移自由基聚合(ATRP)是一种可控自由基合成技术,与普通的自由基技术相比,ATRP技术使凝胶聚合物网链的均匀性提高,更为重要的是通过引发剂的结构设计可以得到不同结构与性能的水凝胶。综述了线形、支化、无机等不同结构ATRP引发剂在水凝胶研究中的进展,并分析了ATRP技术提高凝胶网络均匀性的机理。Atom transfer radical polymerization （ATRP） is a control/＂living＂ polymerization technique. The use of the technique is conductive to obtain hydrogels with target architecture by initiator design, and the same time the uniformity of the hydrogel networks is improved. The progress in application of ATRP in hydrogel preparation is reviewed with regard to initiators with different architectures such as linear, branched and inorganic structures. The mechanism of formation of a hydrogel networks by ATRP is also analyzed.
