摘要:
Alkoxylated natural oils are useful for preparation of water-blown polyurethane foams and can replace polyols and emulsifiers generally used in the art to provide polyol compositions having greater shelf-stability and blend-stability. Methods for preparing polyol compositions useful for preparation of water-blown polyurethane compositions, for preparing the polyurethane compositions using the polyol compositions, and kits comprising the polyol compositions are also described.
