Abstract

Un procedimiento para producir un poliuretano elastómero, que comprende hacer reaccionar: (I) un polioxialcohilen-polioxietilen-poliol normalmente líquido que consta esencialmente de: (1) bloques de polioxialcohileno que constan de grupos oxialcohileno que contienen al menos 3 átomos de carbono, (2) bloques de polioxietileno que constan de grupos oxietileno, que bloquean los extremos de al menos el 35% en moles de tales bloques de polioxialcohileno y que están terminados por grupo hidroxilos primarios, y (3) el residuo de al menos un iniciador, teniendo dicho poliol: (a) de 90 a 97% en peso de tales bloques de polioxialcohileno y de 10 a 3% en peso de tales bloques de polioxietileno, basado en el peso total de tales bloques en el poliol, (b) una media de al menos 3,2 grupos hidroxilo por molécula, (c) un índice de hidroxilo no superior a 45 y (d) al menos 35% en moles de grupos hidroxilos primarios, basado en los moles totales de grupos hidroxilos en el poliol; y (II) un poliisocianato orgánico en presencia de (III) un catalizador para la reacción de (I) y (II), a fin de producir el poliuretano.
