Abstract
L'invention concerne un procédé de préparation de mousses flexibles de polyuréthane ayant une souplesse extrêmement élevée, par réaction d'un polyisocyanate avec un composé hydroxylé, en présence de catalyseurs, d'agents gonflants et autres additifs. Selon l'invention, on utilise, comme composé hydroxylé, un polyol-polyéther A libre, contenant de 75 % à 90 % en poids d'oxyde d'éthylène, et qui présente les caractéristiques suivantes : - fonctionnalité égale ou supérieure à 2, mais de préférence comprise entre 3 et 4; - poids moléculaire équivalent compris entre 700 et 2 000 par groupe hydroxyle; - teneur en groupes hydroxyles primaires, par rapport au total des groupes hydroxyles, comprise entre 2 % et 35 %; et enfin - rapport de la teneur en oxyde d'éthylène/groupes hydroxyles primaires compris entre 2,1 et 42,5. Comme polyisocyanate, on utilise le produit de la polymérisation partielle du toluène-diisocyanate avec des polyols-polyéthers B contenant de l'oxyde de propylène et éventuellement de l'oxyde d'éthylène jusqu'à 3 % en poids du mélange des deux oxydes, le polyisocyanate et les polyols-polyéthers étant utilisés en des quantités telles que le rapport NCO/OH entre le nombre de groupes isocyanate et le nombre de groupes hydroxyles soit supérieur ou égal à 1. L'invention permet notamment d'obtenir des mousses flexibles de polyuréthane ayant une très faible portance.
