HIGHLIGHT: Multiblock Copolymers: PEO Stuck in the Middle
Robert B. Grubbs
A rare example of ABC triblock copolymer with poly(ethylene oxide) as the central block was recently reported. The copolymer was effectively prepared through the combination of living anionic polymerization, atom transfer radical polymerization, and polymer modification. This method will prove to have a great deal of versatility in allowing the incorporation of PEO blocks in interior positions of block copolymers.
