随着高分子化学的进步,特别是可控自由基聚合反应的发现,不同拓扑结构聚合物的合成己获得了巨大的进展.为合成这些复杂结构的聚合物,人们成功地研究了不同的聚合方法.其中,不同功能团引发剂方法是较为方便和可行的方法之一,并且已广泛用于不同结构聚合物的合成.本文综述了用该方法合成不同拓扑结构聚合物,包括嵌段、杂臂星形、H-形、π-形、接枝和环状聚合物所取得的进展,特别强调的是这篇论文没有覆盖这方面的所有研究工作.这一合成方法的思路是基于将不同聚合反应,尤其是不同可控聚合反应相结合,或者将可控聚合与不同的偶合反应,例如与点击反应、Diel-Alder反应和活性酯反应等相结合.所讨论的多功能引发剂不仅包括小分子化合物,也包括带有两个和两个以上引发基团或链转移基团的聚合物.后者称为大分子多功能团引发剂,可以独立引发不同的聚合反应.
With the progress of polymer chemistry, especially the discovery of controlled radical polymerization, great progress has been made in the synthesis of polymers with different topologies.In order to synthesize these complex structure polymers, different polymers have been successfully studied Method.Among them, different functional group initiator methods are one of the more convenient and feasible methods, and have been widely used in the synthesis of different structural polymers.In this paper, the synthesis of different topological polymers, including block, miscellaneous Arm star, H-shape, π-shaped, grafted and cyclic polymers, with particular emphasis on the fact that this paper does not cover all the research in this area.The idea of this synthesis method is based on the difference Polymerization, especially different controlled polymerizations, or controlled polymerizations with different coupling reactions such as click reaction, Diel-Alder reaction and active ester reaction, etc. The multifunctional initiators discussed include not only Small molecule compounds also include polymers with two or more initiating groups or chain transfer groups, referred to as macromolecular multifunctional group initiators that can be independently initiated With polymerization.
