  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.

  β-氨基-β-丙内酰胺衍生物、一种湿气固化聚氨酯组合物及其用途。这种组合物的优异之处在于它具有良好的贮存稳定性，并能在大气湿气中快速固化而不起泡。更具体地说，本发明涉及通过缩合特定的二仲胺（如哌嗪或 1，3-(4、4'-二哌啶基）丙烷与含有 3 个或 3 个以上碳原子的单醛（如异丁醛或 2-苯基丙醛）缩合，然后将形成的缩合物与单异氰酸酯（如苯基异氰酸酯）或二异氰酸酯与低级单醇的等摩尔反应产物反应。本发明还涉及一种湿气固化型聚氨酯组合物，该组合物包含上述衍生物和多异氰酸酯和/或以异氰酸酯基团为末端基团的聚氨酯预聚物，还涉及通过将上述组合物与各种添加剂复配制备的湿气固化型密封材料、墙体材料和防水材料，具体取决于最终用途。
