    摘要: A moisture curable polyurethane composition comprising a polyaldimine represented by the formula (I): Y(̵N = CH - X) n
    wherein X is an aryl group having from 6 to 15 carbon atoms, Y is a divalent or trivalent hdyrocarbon group having from 2 to 15 carbon atoms or a divalent or trivalent polyoxyalkylene group having a molecular weight of from 70 to 6000, and n is an integer of 2 or 3, and a polyisocyanate and/or a polyurethane prepolymer having 2 or more isocyanate groups; and a water proof material, flooring material, sealing material, wall covering material and paint comprising said composition and various fillers, are disclosed. The polyurethane composition has excellent storage stability and quick rate of curing in application.
