Abstract

The present invention relates to polyether compounds, active hydrogen compounds and resin-forming compositions composed of the polyols, and methods for producing foams by employing the active hydrogen components. These polyether compounds have a decreased number of moles of added EO thereby maintaining the hydrophobicity and have sufficient reactivity as polyol components of resins, thereby having high reaction rates. Therefore, it is possible to provide resins having excellent resin properties (tensile strength, flexural strength, water-absorption swelling ratio, etc.).
