Abstract

Procedimiento para la obtención de materiales espumados inencogibles, conteniendo grupos uretano, por reacción de compuestos conteniendo como mínimo dos átomos de hidrógeno activo, del peso molecular 400 hasta 100.000 con poliisocianatos, en resencia de agua y/o agentes de propulsión orgánicos, compuestos de silicio y en caso dado en presencia de catalizadores y ulteriores agentes auxiliares, caracterizado porque como compuestos de silicio se emplean mezclas de compuestos de fórmula general **Fórmula** donde R significa un resto alquilo o bien alquenilo con hasta 3 átomos de carbono, R2 significa un resto clorometilo, R'' significa un resto R2 significa un resto clorometilo, R'' significa un resto R2 o bien R, n'' es un número entero o fraccionado de 0 hasta 9, n es un número entero o fraccionado de 0 hasta 9 y n + n'' significan 10, y R1 se vuelve igual a R2 cuando n'' es 0, en cantidades de un 0,01 hasta 2,0% en peso, referido a los compuestos que llevan átomos de hidrógeno activo del peso molecular 400 - 100.000.
