Abstract
Procédé de préparation de dispersions ou solutions aqueuses de polyuréthannes utilisables dans la préparation d'articles planiformes réticulés. On fait réagir des prépolymères ponant des groupes isocyanate dans les positions terminales, ayant un poids moléculaire moyen inférieur à 15 000 et contenant de 2 à 30 % de motifs oxyde d'éthylène -CH2 -CH 2 -O- à l'intérieur d'une chaîne de polyéthers avec une solution aqueuse d'ammoniac ou une amine primaire à une température de 10 à 70 degrés C en ajoutant l'ammoniac ou l'amine au prépolymère et en utilisant une quantité d'eau au maximum de 10 % du poids total du mélange de réaction après quoi on forme la dispersion ou solution aqueuse recherchée à une concentration de à 65 % en poids par addition d'eau à une température de 10 à 70 degrés C. Les dispersions ou solutions aqueuses selon l'invention possèdent toutes les applications connues pour les dispersions aqueuses de polyuréthannes.
