中文摘要：

聚乙二醇（PEG）负载的催化剂具有较高的催化活性。易于回收和循环使用，因此受到人们极大的关注．此外，PEG可以用作催化反应的流动相动态地担载催化剂，通过“均相反应，两相分离”实现均相催化剂的简单分离．对这一领域的研究进展作一综述．

英文摘要：

PEG-supported catalysts to exhibit high catalytic activity have gained significant attention. They can be recovered and reused conveniently. Furthermore, PEG could be used as a mobile phase supporting catalyst movably. The simple separation of homogeneous catalysts could be realized through monophasic catalysis coupled with biphasic separation. This paper reviews the advances in this research field.
