β-Amino-β-propiolactam derivatives, a moisture-curable polyurethane composition, and use thereof. This composition is excellent in that it possesses good storage stability and can be rapidly cured with moisture in the atmosphere without foaming. More particularly, the present invention relates to B-amino-β-propiolactam derivatives prepared by condensing a specified di-secondary amine such as piperazine or 1,3-(4,4'-dipiperidyl)propane with a monoaldehyde containing 3 or more carbon atoms such as isobutyraldehyde or 2-phenylpropionaldehyde, and reacting the formed condensate with a monoisocyanate such as phenyl isocyanate or an equimolar reaction product between a diisocyanate and a lower monoalcohol. The present invention also relates to a moisture-curable polyurethane composition comprising said derivative and polyisocyanate and/or polyurethane prepolymer having isocyanato groups as terminal groups, and further moisture-curable sealing materials, wall materials, and waterproofing materials prepared by compounding said composition with various additives depending upon the end-use.
