Abstract

a. Procédé de préparation d'élastomère d'uréthane. b. L'invention concerne un procédé de préparation d'élastomères d'uréthane en une seule etape. On fait réagir un polyisocyanate organique avec : 1. un polyol à chaîne présentant un poids moléculaire de 400 à 5 000, 2. une amine aromatique et 3. un polyol présentant au moins une liaison uréthane et/ou un amino-alcool présentant au moins une liaison uréthane. c. Applications du procédé en une seule étape à la fabrication d'articles moulés avec une productivité élevée.
