Abstract

1. UN PROCEDIMIENTO PARA PREPARAR UNA COMPOSICION DE POLIISOCIANATO LIQUIDA Y ESTABLE DURANTE EL AL- MACENAMIENTO CARACTERIZADO PORQUE COMPRENDE LAS E- TAPAS DE (1) CALENTAR UNA MEZCLA DE UN POLIISOCIA- NATO Y UN FOSFATO ACIDO A UNA TEMPERATURA EN EL INTERIOR DE 60 A 190 GRADOS CENTIGRADOS DURANTE UN TIEMPO TAL QUE NO SE PRODUCE SEPARACION DE LAS FA- SES CON EL ENFRIAMIENTO DE LA MEZCLA DE REACCION HASTA TEMPERATURA AMBIENTE, EN QUE LA MEZCLA CON- TIENE GASES DISUELTOS; Y (2) SOMETER LA MEZCLA A UNA PRESION NEGATIVA SUFICIENTE PARA ELIMINAR POR LO MENOS UNA PORCION DE LOS GASES DISUELTOS DE LA MISMA.1. A PROCEDURE FOR PREPARING A STABLE AND LIQUID POLYISOCIANATE COMPOSITION DURING STORAGE CHARACTERIZED BECAUSE IT INCLUDES THE STAGES OF (1) HEATING A MIXTURE OF A POLYISOCYANATE AND A PHOSPHATE ACIDED TO A TEMPERATURE INSIDE 60 190 DEGREES DEGREE DURING A TIME SUCH THAT NO SEPARATION OF THE PHASES OCCURS WITH THE COOLING OF THE REACTION MIXTURE UNTIL ENVIRONMENTAL TEMPERATURE, IN WHICH THE MIXTURE CONTAINS DISSOLVED GASES; AND (2) SUBMIT THE MIXTURE TO A NEGATIVE PRESSURE SUFFICIENT TO ELIMINATE AT LEAST A PORTION OF THE DISSOLVED GASES OF THE SAME.
