CA 2455503

The present invention is to the production of flexible polyurethane foam in the absence of an amine catalyst. The reactivity of the foam forming system can be controlled by the addition of an autocatalytic polyol containing a tertiary amine where the amount of autocatalytic polyol comprises less than 5 percent by weight of the total polyol.

La présente invention concerne un procédé de production de mousse polyuréthanne souple en l'absence d'un catalyseur aminé. On peut contrôler la réactivité du système de formation de la mousse par l'ajout d'un polyol autocatalytique contenant une amine tertiaire, la quantité de polyol autocatalytique comprenant moins de 5 % en poids du polyol total.
