Abstract
A novel one-pot methodology combining anionic polymerization and polyhomologation, through a "bridge" molecule (BF3OEt2), was developed for the synthesis of polyethylene (PE)-based block copolymers. The anionically synthesized macroanion reacts with the "bridge" molecule to afford a 3-arm star (trimacromolecular borane) which serves as an initiator for the polyhomologation.
摘要
发展了一种新颖的一锅法聚合方法，结合阴离子聚合和多同系化反应，通过“桥”分子（BF3OEt2）合成基于聚乙烯（PE）的嵌段共聚物。阴离子合成的大分子阴离子与“桥”分子反应，得到 3 臂星（三大分子硼烷），作为多同系化反应的引发剂。
