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.
