Abstract

L'invention a pour objet un procédé de fabrication de polyuréthanes résistant l'inflammation. Ce procédé consiste, dans une première étape, à fixer de l'oxyde de propylène sur de l'urée en solution dans un solvant de caractère basique, puis, dans une seconde étape, à faire réagir la solution d'urée oxyalcoylénée avec un ou plusieurs polyisocyanates organiques. Le procédé est particulièrement applicable à la fabrication de mousses rigides de polyuréthane.
