Abstract

Composition qui permet de produire un élastomère à l'aide de prépolymères à base de diisocyanate de toluène. Ladite composition est préparée par mélange (a) d'un polyisocyanate, (b) d'un composé de réticulation et (c) d'un catalyseur constitué essentiellement de 1,8-diazabicyclo(5,4,0)undéc-7-ène. Le polyisocyanate, qui constitue au moins 70 % en poids de la composition contenant de l'isocyanate, est un prépolymère à terminaison diisocyanate de toluène contenant moins d'environ 2 % en poids de monomère de diisocyanate de toluène libre, et le composé de réticulation contient des composés possédant des groupes réactifs à l'isocyanate, au moins 40 % en poids des composés possédant des groupes réactifs à l'isocyanate étant des composés pourvus d'au moins un groupe hydroxyle.
