Abstract

METODO DE PREPARACION DE UN CONCENTRADO MICRIENCAPSULADO DE UN ACIDO DE LEWIS. COMPRENDE LAS OPERACIONES DE DISPERSAR Y MANTENER GOTITAS, DISPERSAS DE UN ACIDO DE LEWIS CON GLICEROL EN UN MEDIO LIQUIDO, Y LA POSTERIOR INCORPORACION AL MEDIO LIQUIDO DE UNA COMPOSICION QUE INCLUYE UN POLISOCIANATO AROMATICO Y UN POLIEPOXIDO CICLOLIFATICO. COMO RESULTADO DE LAS OPERACIONES ANTERIORES TIENE LUGAR UNA POLICONDENSACION INTERFACIAL EN LA SUPERFICIE DE LAS GOTITAS PARA FORMAR UNA MEZCLA DE MICROCAPSULAS IMPERMEABLES, SUSCEPTIBLES DE ROMPERSE, Y CUYO DIAMETRO MEDIO PUEDE ESTAR COMPRENDIDO ENTRE 0,1 Y 400 MICROMETROS. EL MEDIO LIQUIDO EMPLEADO SE SELECCIONA ENTRE POLISOCIANATOS AROMATICOS Y ESTERES DE ACIDO CARBOXILICO AROMATICO Y ALCOHOL ALQUILICO, ARALQUILICO Y ARILICO. ES DE EMPLEO EN LA OBTENCION DE CATALIZADORES LATENTES BASADOS EN UN ACIDO DE LEWIS. R
