Abstract

Un procedimiento para la preparación de un poliuretano que comprende mezclar y hacer reaccionar tres compuestos de hidrógeno activo con un poliisocianato o poliisotiocianato orgánico, caracterizado por que uno de los compuestos de hidrógeno activo tiene una reactividad con un pollisocianato mayor que la reactividad de cualquiera de los otros dos compuestos de hidrógeno activo, siendo el parámetro de solubilidad de cada compuesto de hidrógeno activo diferente del de cada uno de los otros en un valor mayor que 0,49 cuando el número de equivalente de hidrógeno activo del segundo compuesto de hidrógeno activo más reactivo es mayor que el número de equivalentes de hidrógeno activo del compuesto de hidrógeno activo más reactivo, teniendo el poliuretano así preparado un factor de módulo de flexión (-29ºC/70ºC) no mayor que 3,4 y teniendo al menos tres temperaturas de transición térmica enter -100ºC y la temperatura de descomposición del poliuretano tal como se determina por análisis termomecánico.
