摘要： A water-soluble polyurethane which is obtained from a water-soluble polyalkylene glycol, a polyisocyanate, and a comb-shaped hydrophobic diol represented by the general formula (1). The polyurethane is usable as an extrusion-molding aid for cement materials, thickener for mortars, thickener for underwater concretes, binder for ceramic molding, and humectant for hair cosmetics. (In the formula (1), R1 represents a hydrocarbon group; R?2 and R3¿ each represents a hydrocarbon group, etc.; X, X', and X each represents alkylene, etc.; Z and Z' each represents oxygen, etc.; R4 represents alkylene; k is 0 to 15; and n and n' each is 0 to 15).
