Abstract: The residual transition-metal catalyst in atom transfer radical polymerization (ATRP) system may cause process and environment issues，that will restrict its commercialization. In this paper，several immobilized catalyst systems，including silica or quartz，cross-linked polystyrene or other polymers used as the immobilized catalysts of ATRP are summarized. They can solve part of the residual catalyst problem，but these approaches have some limitations. An immobilized/soluble hybrid ATRP system was developed to overcome this difficulty，and no noticeable differences between hybrid and conventional homogeneous catalyst were observed. This result indicates that immobilized/soluble hybrid catalyst system can be applicable to various ATRP systems.

摘要： 综述了几种原子转移自由基聚合（ATRP）用负载化催化体系的组成及应用，主要包括硅胶或石英、交联聚苯乙烯或其它聚合物为载体进行的催化剂负载化，它们都能够部分解决催化剂残留问题，但却有一定的局限性；负载/可溶性混杂催化体系成为解决这一问题的新方法，而且它与传统的均相催化体系相比，可控性没有明显差异，有希望作为未来解决催化剂残留的有效方法。最后展望了ATRP负载化催化剂的发展方向。
