摘要：
Well defined poly(ethylene oxide)s were prepared using yttrium isopropoxide as an initiator. End group analysis using H-1- and C-13 NMR spectroscopy revealed that only polymers with isopropyl ether and hydroxyl end groups were produced. The molecular weight is controlled by the initial amount of initiator added and low polydispersity polymer ((M) over bar(w)/(M) over bar(n) approximate to 1.1) was isolated. Sequential polymerization indicated the suitability of this initiator for macromolecular engineering.
