Abstract
La presente invención se refiere a procedimiento de una sola etapa para la obtención de poliaminas preferentemente de elevado peso molecular con grupos amino primarios mediante hidrólisis de compuestos que preentan grupos NCO, en disolventes orgánicos que contienen agua con adición de catalizadores básicos, caracterizado porque se hidrolizan a temperaturas de 40 a 170 grados C; a) compuestos que presentan grupos NCO, preferentemente grupos NCO enlazados aromáticamente, con un contenido en NCO de 0,5 hasta 40 por ciento en peso, preferentemente prepolímeros NCO con un contenido en NCO de 1,2 a 25 por ciento en peso, o poliisocianatos modificados con un contenido en NCO de 1,5 a 20,5 por ciento en peso, b) con 0,75 a 40 moles de agua por equivalente de NCO del componente a); c) en presencia de 0,021 a 0,099 por ciento en peso, preferentemente de 0,03 a 0,099 por ciento en peso, referido al 100 por ciento en peso del componente a), de hidróxido sódico, como catalizador básico, d) y en presencia de 10 por ciento en peso, referido al 100 por ciento en peso del componente a), de disolventes orgánicos polares miscibles con agua con grupos nitrilo, cetona, sulfóxido o éter y con un margen de ebullición de 56 a 250 grados C; e) con mantenimiento de una fase de reacción homogénea.
