摘要： The invention relates to a polyether polyol composition for the preparation of polyurethane foams, comprising: (a) a polyether polyol having a hydroxyl functionality of 2, an OH number within a range of from 50 to 65 mg of KOH/g and a proportion of primary hydroxyl groups within a range of from 40 to 80%, based on the total number of primary and secondary hydroxyl groups, having a PO content of from 45 to 55% by weight and an EO content of from 40 to 55% by weight; (b) a dispersion of a polymer in a polyether polyol, wherein the OH number of the dispersion is within a range of from 10 to 30 mg of KOH/g and the polyether polyol has a hydroxyl functionality of 3, a proportion of primary hydroxyl groups within a range of from 70 to 90%, based on the total number of primary and secondary hydroxyl groups, a PO content of from 70 to 90% by weight and an EO content of from 10 to 30% by weight; (c) a polyether polyol having a hydroxyl functionality of 3, an OH number within a range of from 220 to 290 mg of KOH/g and a proportion of primary hydroxyl groups within a range of at least 90%, based on the total number of primary and secondary hydroxyl groups, having a PO content of up to 2% by weight and an EO content of at least 75% by weight; (d) a polyether polyol having a hydroxyl functionality of 2, an OH number within a range of from 50 to 70 mg of KOH/g and a proportion of primary hydroxyl groups within a range of from 0 to 3%, based on the total number of primary and secondary hydroxyl groups, having a PO content of at least 95% by weight and an EO content of up to 3% by weight.
