Abstract

Un proceso para la produccion de microcápsulas que contienen un material acuoso dentro de una cubierta polimérica, que comprende (a) proporcionar unafase acuosa que comprende un material a ser encapsulado, y un prepolímero de urea-formaldehidoy/o melamina-formaldehido disuelto en la misma; (b) crear unaemulsion de dicha fase acuosa en una fase líquida orgánica continua que comprende uno o más solventes orgánicos y uno o más agentes tensioactivos,donde la emulsion comprende gotasd iscretas de la fase acuosa dispersada en la fase líquida orgánica continua, allí siendo formada por la misma unainterfase entre las gotas discretas de la fase acuosa y la fase líquida orgánica continua; y (c) causar in situ unaautoconden sacion del prepolímero enla fase acuosa de las gotas discretas adyacentes a la interfase al calentar la emulsion a una temperatura de aproximadamente 20 a 100°C en la presenciade un catalizador de transferencia de proton de superficieactiva que es soluble en el líquido orgánico pero solamente levemente soluble en la faseacuosa por un período suficiente de tiempo para permitir un acabado sustancial de la condensacion in situ del prepolímero para convertir lasgotasde líqui do de la fase acuosa en cápsulas que consisten de polímero permeable solidas que encierran el medio acuoso, microcápsulas y suspension demicrocápsulas obtenidas por dicho procedimiento y formulacion pesticida envasada.
