Abstract

L'invention concerne des polyols de polyéther, conçus pour la préparation de mousse polyuréthanne rigide, au moyen d'un procédé mettant en oeuvre des catalyseurs imidazole. Ces catalyseurs ne perdent pas leur réactivité à des températures élevées et on peut les utiliser à ces températures élevées pour préparer des polyols, diminuant ainsi le temps de séjour et la consommation d'énergie dans les procédés de production de polyols.
