Abstract
LA PRESENTE INVENCION TIENE POR OBJETO LA MICROENCAPSULACION POR POLIADICION INTERFACIAL. MAS CONCRETAMENTE CONCIERNE A LA PREPARACION DE MICROCAPSULAS CUYA PARED ESTA CONSTITUIDA DE POLIUREA, POR POLIADICION INTERFACIAL, CONSISTIENDO EN EMULSIONAR EN UN LIQUIDO ESENCIALMENTE ACUOSO UN LIQUIDO HIDROFOBO CONTENIENDO UN POLIISOCIANATO Y EVENTUALMENTE UN PRODUCTO ORGANICO DISUELTO, LUEGO FORMAR LAS PAREDES DE LAS MICROCAPSULAS POR ADICION DE UNA POLIAMINA, ESTANDO CARACTERIZADO DICHO PROCEDIMIENTO PORQUE EL POLIISOCIANATO COMPRENDE: -UN DIISOCIANATO ALIFATICO -Y EL TRIMERO EN CICLO ISOCIANURATO DE UN DIISOCIANATO ALIFATICO. EL PRESENTE PROCEDIMIENTO ES PARTICULARMENTE INTERESANTE PARA LA PREPARACION DE SUSPENSIONES DE MICROCAPSULAS CONTENIENDO UN COLORANTE, QUE SON UTILIZADAS PARA FABRICAR PAPELES SIN CARBONO.
