Abstract: front page image
(EN)The present invention is directed to a membrane, comprising a polyurethane (PU1), wherein the polyurethane (PU1) is based on 80 to 100 % by weight of a mixture of at least one diol (D1) and at least one polyisocyanate (I1), and 0 to 20 % by weight of at least one compound (C1) with at least two functional groups which are reactive towards isocyanate groups. Furthermore, the present invention is directed to a process for preparing a membrane, comprising providing a solution (L1) at least comprising a polyurethane (PU1) and preparing a membrane from solution (L1) using phase inversion; as well as the use of a membrane according to the present inven- tion for coating a woven article.
(FR)La présente invention concerne une membrane, comprenant un polyuréthane (PU1), le polyuréthane (PU1) étant basé sur 80 à 100 % en poids d'un mélange d'au moins un diol (D1) et au moins un polyisocyanate (I1), et 0 à 20 % en poids d'au moins un composé (C1) comportant au moins deux groupes fonctionnels qui sont réactifs avec les groupes isocyanate. En outre, la présente invention concerne un procédé de préparation d'une membrane, comprenant la fourniture d'une solution (L1) comprenant au moins un polyuréthane (PU1) et la préparation d'une membrane à partir de la solution (L1) au moyen d'une inversion de phase ; ainsi que l'utilisation d'une membrane selon la présente invention pour revêtir un article tissé.
