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.at. Process for preparing urethane elastomer. b. The invention relates to a process for the preparation of urethane elastomers in one step. An organic polyisocyanate is reacted with: 1. a chain polyol having a molecular weight of 400 to 5,000, 2. an aromatic amine and 3. a polyol having at least one urethane bond and / or an amino alcohol having at least a urethane bond. vs. Applications of the one-step process to the manufacture of molded articles with high productivity.
