摘要
主要介绍了用大分子引发剂法制备嵌段共聚物的方法。大分子引发剂是从已商品化的功能聚合物制得或用其它活性聚合方法合成。从单封端的端羟基聚合物、其它单官能团或双官能团聚合物以及双功能基团缩聚物制得大分子引发剂 ,然后用于原子转移自由基聚合 (ATRP)、氮氧稳定自由基聚合以及可逆加成裂解链转移 (RAFT)聚合等 ,可制得结构可控、分子量分布窄的嵌段共聚物。
In this article, some approaches of synthesizing block copolymers with macroinitiator method were introduced briefly. The macroinitiators are prepared from functional polymers available commercially or obtained by other living polymerizations. The macroinitiators synthesized from mono-hydroxyl-terminated polymers, other mono-and difunctional polymers and difunctional condensation polymers were used in ATRP polymerization, nitroxide-mediated polymerization and RAFT, to obtain well-defined block copolymers. \;
