Abstract
Un método para preparar una espuma de poliuretano flexible, que muestra una alta resistencia al deterioro inducido por el calor, haciendo reaccionar un polieter-poliol con un isocianato polifuncional, en presencia de un agente de expansión y de una, cantidad catalíticamante eficaz de una composición catalítica de gelificación que contiene estaño, fósforo y un halógeno en forma químicamente combinada en un solo compuesto, que contiene de 3 a 30% en peso de estaño, de 2 a 20% en peso de fósforo y de 3 a 70% en peso de un halógeno seleccionado del grupo que consiste en cloro, bromo y yodo, donde dicho compuesto es un éster de monoórganoestaño o de diórganoestaño de un compuesto de fósforo seleccionado del grupo que consiste en ácido fosfórico, ácido fosfóroso, ácido fosfónico, ácido fosfínico, ácido tiofosforoso y cloruro de fosforilo.
