Abstract
Un procedimiento perfeccionado para la obtención de poliuretanos que comprende las etapas de: (a) mezclar entre sí, en proporciones reactivas, un poliisocianato orgánico y un compuesto que tenga grupos terminales que contengan hidrógeno activo, junto con (b) una cantidad catalítica de un sistema de catalizador de organoestaño, para catalizar la reacción de los componentes de (a), comprendiendo dicho sistema de catalizador una mezcla de un óxido de bis(tri-n-alcohil-estaño) y el producto de reacción de un óxido de dialcohil-estaño con un ácido carboxílico.
