DIVALENT PHOSPHAZENIUM SALT AND POLYALKYLENE OXIDE COMPOSITION CONTAINING SAME, AND POLYURETHANE-FORMING COMPOSITION CONTAINING SAID POLYALKYLENE OXIDE COMPOSITION

摘要

Provided are a divalent phosphazenium salt which is neutral and has excellent thermal stability and aldehyde scavenging ability, and a method for producing the same. Also provided are a polyalkylene oxide composition having a reduced volatile aldehyde level, suppressed odor and turbidity, and excellent urethanization reactivity, a method for producing said polyalkylene oxide composition, and a polyurethane-forming composition containing said polyalkylene oxide composition. A divalent phosphazenium salt having a specific structure. Also, a polyalkylene oxide composition containing a divalent phosphazenium salt having a specific structure and a polyalkylene oxide, a method for producing the same, and a polyurethane-forming composition containing the same.
