Claim Text:
1. A polyol blend comprising: 1) from 5 to 40% by weight, based on 100% by weight of said polyol blend, of one or more monofunctional polyethers having a hydroxyl number of less than or equal to 28 mg KOH/g; and containing from 2 to less than or equal to 20% of copolymerized oxyethylene, based on the total weight of said monofunctional polyether; 2) from 2 to 80% by weight, based on 100% by weight of said polyol blend, of one or more polyether polyols having a functionality of from 2 to 8, a hydroxyl number of from 20 to 240 mg KOH/g and containing at least 50% of copolymerized oxyethylene, based on the total weight of said polyether polyol 2); 3) from 10 to 70% by weight, based on 100% by weight of said polyol blend, of one or more polyether polyols having a hydroxyl number of from 47 to 300 mg KOH/g, a functionality of from 2 to 8, and containing from 5 to 45% of copolymerized oxyethylene, based on the total weight of said polyether polyol 3), wherein said polyether polyols do not contain pure EO terminal blocks; and 4) from 0 to 50%, based on 100% by weight of said polyol blend, of a polyether polyol having a hydroxyl number of from 10 to 45 mg KOH/g and a functionality of from 2 to 8.
