ABSTRACT:
Polyol blend compositions are provided containing a polyester polyol, especially an aromatic polyester polyol, a compatibilizing block copolymer of ethylene oxide and at least one other alkylene oxide having three or more carbon atoms in the molecule, the block copolymer being terminated by ethylene oxide blocks, and optionally other polyols. The blends are miscible with halohydrocarbon blowing agents such as trichlorofluoromethane and suitable for reaction with polyisocyanates to give polyisocyanurate and polyurethane foams.
