Abstract
L'invention concerne un procédé catalysé par une amine pour préparer des uréthanes. Dans un procédé de préparation de polyuréthanes, on utilise une quantité catalytique d'un produit de la réaction d'une N,N-(aminodisubstitué) alkylène-amine et d'un oxyde d'alkylène. L'invention s'applique en particulier à la préparation de mousses de polyuréthane n'ayant pas d'odeur d'amine, même immédiatement après leur préparation.
