摘要： This invention generally provides composition for making a polyurethane foam with reduced aldehyde emission and more specially to composition useful in means of transport such as interior part of cars, wherein composition is comprising: (a) a polyfunctional isocyanate; (b) an isocyanate reactive composition; and (c) a compound of the formula (I) or (II), wherein the compound (c) is present by weight percentage in the composition in an amount ranging from about 0.001 to about 10, preferably from about 0.01 to about 5, and more preferably from about 0.05 to about 2 based on the total weight of the composition. The compositions can reduce aldehyde emission, especially acetaldehyde emission in the PU foam and has no obvious influence on the mechanic properties of the foam.
