Poly(ethylene oxide) (PEO) is a kind of multifunctional water-soluble polymer which was prepared by ring opening polymerization of ethylene oxide. PEO can be widely used for its excellent properties. The typical characteristics and research progress of PEO were introduced briefly in this article. Various catalyst systems of PEO were reviewed. The catalytic mechanism of the polymerization of EO was described here. Alkaline earth metal ammoniate system
alkyl metal catalyst system and alkoxy metal catalyst system which have potential industrial application were presented emphatically. The prospect of technology and application of PEO was also discussed.
