Abstract

El objeto de la presente invención es un procedimiento para preparar espumas de poliuretano a partir de A1 compuestos que presentan átomos de hidrógeno que pueden reaccionar frente a isocianatos con un peso molecular de 400 - 15.000, A2 compuestos que dado el caso presentan átomos de hidrógeno que pueden reaccionar frente a isocianatos con un peso molecular de 62 - 399, A3 agua y/o agente de expansión físico, A4 dado el caso coadyuvantes y aditivos, A5 compuestos con al menos un grupo semicarbazida, y B di o poliisocianatos, que conduce a espumas de poliuretano con emisión de formaldehído reducida y en el que no se ve influenciada esencialmente la actividad de la mezcla de materia prima y en el que no se ven influenciadas negativamente las propiedades mecánicas de la espuma resultante (especialmente la deformación permanente y el comportamiento de envejecimiento por humedad).
