摘要
Highly monodisperse, heterobifunctional poly(ethylene glycol) (PEG) was prepared by iterative chain extension of a PEGylated homostar using an octagol (EG(8)) building block to give MeO-EG(24)-OH in high purity. The branched structure facilitated purification of intermediates by chromatography, and mono-functionalization of the chain termini. This approach should be extendable to other classes of oligomers.
