Title (EN) THERMOPLASTIC POLYURETHANE
(FR) POLYURÉTHANE THERMOPLASTIQUE
(DE) THERMOPLASTISCHES POLYURETHAN
Abstract:
(EN) The present invention relates to thermoplastic polyurethanes, which are obtainable or obtained by the reaction of at least one polyisocyanate composition, at least one chain extender (KV1) of general formula (I), and at least one other chain extender (KV2) selected from the group consisting of compounds with at least two isocyanate-reactive groups with a molecular weight of <500 g/mol, and at least one polyol composition. The present invention further relates to a method for producing such thermoplastic polyurethanes and to the use of a thermoplastic polyurethane or of a thermoplastic polyurethane obtainable or obtained according to a method of the invention for producing extruded products, films and moldings.
(FR) La présente invention concerne des polyuréthanes thermoplastiques pouvant être obtenus ou obtenus par mise en réaction d'au moins une composition de polyisocyanate, d'au moins un allongeur de chaîne (KV1) de formule générale (I) et d'un autre allongeur de chaîne (KV2R2) choisi dans le groupe constitué par les composés comportant au moins deux groupes réactifs vis-à-vis des isocyanates ayant un poids moléculaire < 500 g/mol, et d'au moins une composition de polyol. La présente invention concerne en outre un procédé de préparation de polyuréthanes thermoplastiques de ce type ainsi que l'utilisation d'un polyuréthane thermoplastique selon l'invention ou d'un polyuréthane thermoplastique pouvant être obtenu ou obtenu selon un procédé selon l'invention pour la fabrication de produits d'extrusion, de films et de corps moulés.
(DE) Die vorliegende Erfindung betrifft thermoplastische Polyurethane erhältlich oder erhalten durch Umsetzung mindestens einer Polyisocyanatzusammensetzung, mindestens eines Kettenverlängerers (KV1) der allgemeinen Formel (I) und eines weiteren Kettenverlängerers (KV2), ausgewählt aus der Gruppe bestehend aus Verbindungen mit mindestens zwei gegenüber Isocyanten reaktiven Gruppen mit einem Molekulargewicht von <500 g/mol, und mindestens einer Polyolzusammensetzung. Weiter betrifft die vorliegende Erfindung ein Herstellungsverfahren für derartige thermoplastische Polyurethane sowie die Verwendung eines erfindungsgemäßen thermoplastischen Polyurethans oder eines thermoplastischen Polyurethans erhältlich oder erhalten nach einem erfindungsgemäßen Verfahren zur Herstellung von Extrusionsprodukten, Filmen und Formkörpern.
