Abstract

L'invention concerne un procédé servant à préparer des polymères de polyuréthanne par extrusion d'un polyuréthanne liquide coulant (TLP). On prépare ce TLP à partir d'un polyisocyanate et d'un polyol à basse température. On peut produire des polymères de polyuréthanne élastomères à partir du TLP au moyen d'un processus d'extrusion réactive. On peut réitérer le traitement de ces polymères de polyuréthanne élastomères obtenus, un certain nombre de fois sous forme de fusion (traitement en fusion) et on peut ensuite façonner le polymère en différentes formes utiles.
