Abstract
Provided is a catalyst for synthesizing a polyethylene oxide polymer, comprising a crown ether as a first component, a quaternary phosphonium salt as a second component, and an alkali metal and/or an alkali metal compound as a third component. The catalyst can reduce the concentration of alkali metal ions in the product and is suitable for high-standard industrial fields. Also provided is a method for synthesizing a polyethylene oxide polymer, comprising carrying out a reaction of a compound containing active hydrogen and ethylene oxide in the presence of the catalyst. The method is simple to operate and environmentally friendly, improves the quality of the synthesized product, and is suitable for high-standard industrial production.
