摘　　要：遥爪聚合物因为其首末两端的官能团,常常作为交联剂、扩链剂或大分子构筑段,用来制备嵌段、接枝、星形、超支化和树状等聚合物.概述了遥爪聚合物制备方法,包括阴离子活性聚合、阳离子活性聚合、活性自由基聚合、活性易位聚合和活性缩合聚合的研究进展,并分析了各种方法的优劣.Telechelic polymers, which are macromolecules that contain two reactive end groups, are used as cross-linkers, chain extenders, and important building blocks for various macromolecular structures, including block and graft copolymers, star, hyperbranched and dendritic polymers. The general techniques for the preparation of telechelic polymers by controlled/living polymerization methods are described, which include namely living anionic poly- merization, living cationic polymerization, living radical polymerization, living metathesis polymerization and living polycondensation. The advantages and disadvantages of each method are investigated.
