Abstract
SE DESCRIBE UN METODO PARA ESTABILIZAR UN COMPUESTO ISOCIANATO AÑADIENDO 10-5000 PPM DE FENOL AL COMPUESTO DE ISOCIANATO, Y TAMBIEN UN COMPUESTO DE ISOCIANATO ASI ESTABILIZADO. EN LA COMPOSICION DE ISOCIANATO ESTABILIZADA POR EL METODO ANTERIORMENTE EXPUESTO, LOS CAMBIOS DE COLORACION DEPENDIENTES DEL TIEMPO Y LA TURBIDEZ DEBIDA A LA AUTO-POLIMERIZACION SON SUPRIMIDOS DE MODO QUE MUESTRAN UNA ESTABILIDAD EXCEPCIONAL DE ALMACENAMIENTO EN COMPARACION CON EL CORRESPONDIENTE COMPUESTO DE ISOCIANATO QUE CONTENGA UN ESTABILIZADOR CONVENCIONAL.
