Abstract

The present invention relates to a process for the production of polyurethane foams from Al compounds containing isocyanate-reactive hydrogen atoms and having a molecular weight of from 400 to 15,000, A2 optionally compounds containing isocyanate-reactive hydrogen atoms and having a molecular weight of from 62 to 399, A3 water and/or physical foaming agents, A4 optionally auxiliary substances and additives, A5 compounds having at least one semicarbazide group, and B di- or poly-isocyanates which yields polyurethane foams with reduced formaldehyde emission and wherein the activity of the raw material mixture is not substantially affected and wherein the mechanical properties of the resulting foam (in particular compression set and ageing behaviour under humid conditions) are not adversely affected.
