Abstract

L'invention concerne des élastomères polyuréthanes et un procédé de production d'un élastomère polyuréthane à base de polyéthercarbonate polyols. Le procédé comprend une première étape, dans laquelle on fait réagir au moins A) un diisocyanate organique et B) un polyol pour obtenir un prépolymère à terminaison NCO. Dans une deuxième étape, on fait réagir le prépolymère exclusivement avec C) au moins un allongeur de chaîne et/ou agent de réticulation. Les composants B) contiennent au moins un polyéthercarbonate polyol pouvant être obtenu par fixation de dioxyde de carbone et d'oxydes d'alkylène à des substances de départ à fonctionnalité H à l'aide de catalyseurs.
