    Abstract: A cold curing polyurethane composition containing as a curing component an isocyanate-terminated polyurethane prepolymer prepared by reacting an organic polyisocyanate with a polyol mainly comprising a polyoxyalkylene polyol having a molecular weight of 1,500 to 15,000 per unit hydroxyl group and a total degree of unsaturation of 0.07 meq/g or less. Such a polyoxyalkylene polyol is produced preferably by the ring-opening addition polymerization of an alkylene oxide with an initiator in the presence of a double metal cyanide complex catalyst. This composition gives a highly flexible cured article by curing the same with an atmospheric moisture. The use of a high-molecular polyoxyalkylene polyol as the curing agent gives a similar highly flexible cured article. This composition is useful as a sealant or a waterproofing material.
