Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
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.
