Title
(DE) OXAZOLINTERMINIERTE POLYURETHANE
(EN) OXAZOLINE-TERMINATED POLYURETHANES
(FR) POLYURETHANNES A EXTREMITES OXAZOLINE
Abstract
(DE)
Die vorliegende Erfindung betrifft oxazolinterminierte Polyurethane der allgemeinen Formel (I), in der Q der Rest eines verzweigten oder unverzweigten NCO-terminierten PU-Prepolymeren ist, x einen Wert zwischen 0 und 40 aufweist, Z entweder eine direkte Bindung oder die Gruppe CR5R6 bedeutet, die Reste R1 bis R6 jeweils unabhängig voneinander H, Alkyl oder Aryl mit bis zu 8 C-Atomen bedeuten, R7 ausgewählt ist aus der Gruppe Wasserstoff, Methyl oder Ethyl, R ausgewählt ist aus der Gruppe H, Alkyl oder Alkenyl, M ausgewählt ist aus der Gruppe Alkylen, Alkenylen, Arylen und Alkarylen, wobei die Molekülteile R und M jeweils unabhängig voneinander 0 bis 12 C-Atome aufweisen und durch eine Alkoxygruppe mit 1 bis 3 C-Atomen substituiert sein können und n wenigstens 2,0 ist, ein Verfahren zu deren Herstellung sowie diese enthaltende, in der Hitze härtbare Einkomponenten-Polyurethansysteme.
(EN)
The invention concerns oxazoline-terminated polyurethanes of general formula (I) in which Q is a branched or unbranched NCO-terminated PU prepolymer entity, x is a number between 0 and 40, Z is either a direct bond or the group CR5R6, groups R1 to R6, independently of each other, are hydrogen or alkyl or aryl with up to 8 C-atoms, R7 is hydrogen, methyl or ethyl, R is hydrogen, alkyl or akenyl, M is alkylene, alkenylene, arylene or alkylarylene, whereby each of the molecule parts R and M, independently of each other, have a 0 to 12 C-atoms and may be substituted by an alkoxy group with 1 to 3 C-atoms and n is at least 2.0. The invention also concerns a method of producing such polyurethanes, as well as single-component heat-curable systems containing them.
(FR)
L'invention concerne des polyuréthannes à extrémités oxazoline, de formule générale (I), dans laquelle Q est le reste d'un prépolymère PU à extrémités NCO, ramifié ou non ramifié, x a une valeur comprise entre 0 et 40, Z désigne une liaison directe, ou bien le groupe CR5R6, les restes R1 à R6 désignent, indépendamment l'un de l'autre, H, alkyle ou aryle ayant jusqu'à 8 atomes de carbone, R7 est choisi dans le groupe hydrogène, méthyle ou éthyle, R est choisi dans le groupe H, alkyle, ou alcényle, M est choisi dans le groupe alkylène, alcénylène, arylène et alkarylène, les parties de la molécule R et M présentant chacune, indépendamment l'une de l'autre, 0 à 12 atomes de carbone,et pouvant être substituées par un groupe alcoxy de 1 à 3 atomes de carbone et n étant au moins égal à 2,0. L'invention concerne également un procédé de production de ces composés, ainsi que des systèmes à un seul composant, thermodurcissables, contenant ces polyuréthannes.
