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.).
本发明涉及聚醚化合物、活性氢化合物和由聚醚醇组成的树脂成型组合物,以及通过使用活性氢成分制备泡沫的方法。这些聚醚化合物具有降低的EO加入摩尔数,从而保持疏水性,并具有足够的反应性作为树脂的聚醇组分,因此具有高反应速率。因此,可以提供具有优异树脂性能(拉伸强度、弯曲强度、吸水膨胀率等)的树脂。
