Abstract (en)
The invention relates to polyols prepared by reacting ethylene oxide with an initiator followed by additional alkylene oxide. The ethylene oxide blocks at the initiator ranges from 1 to 30 weight percent based on the weight of the polyol. Polyurethane foams prepared from these polyols exhibit good air flow and improved load bearing properties.
