Zusammenfassung:The present invention provides trimerization catalyst compositions having a sterically hindered carboxylate salt used in combination with a tertiary amine catalysts having isocyanate reactive groups and methods to produce a polyisocyanurate/-poly-urethane foam using such trimerization catalyst compositions. La présente invention concerne des compositions catalytiques de trimérisation comprenant un sel carboxylate à encombrement stérique utilisé en combinaison avec des catalyseurs de type amine tertiaire ayant des groupes isocyanate réactifs, et des procédés pour produire une mousse de polyuréthane/polyisocyanurate à l'aide de telles compositions catalytiques de trimérisation.
