Abstract

La presente invención se refiere a un procedimiento para preparar artículos moldeados de poliuretano alásticos usando la polimerización por adición de poliisocianato que consiste de hacer reaccionar: a) un poliisocianato orgánico; b) un compuesto de peso molecular más elevado que tiene por lo menos dos átomos de hidrógeno reactivos; y opcionalmente c) un alcohol multivalente de peso molecular más bajo y/o poliol de polioxialquileno; en presencia de d) un agente interno para facilitar la extracción del molde; e) un catalizador; y opcionalmente f) agentes auxiliares y/o aditivos; en un molde en donde el agente interno para facilitar la extracción del molde consiste de: A) de 0.1 por ciento a 15 por ciento en peso, basado en todo el peso de los componentes (b) y (c), de una mezcla que consiste de (i) de 5 a 80 partes en peso de por lo menos una amina orgánica, y (ii) de 20 a 95 partes en peso de por lo menos una sal de metal del ácido esteárico; y B) de 0.01 por ciento a 32 por ciento e peso, basado en todo el peso de los componentes (b) y (c), de por lo menos un ácido mono- y/o di-carboxílico orgánico o sus anhídridos, en donde el artículo moldeado de poliuretano elástico es principalmente no celular.
