Abstract

SE PRESENTA UN POLVO DE POLIMERO INSOLUBLE EN AGUA QUE PUEDE SER REDISPERSADO EN UNA FASE LIQUIDA ESTE POLVO SE OBTIENE PROCEDIENDO COMO SIGUE: PRIMERO SE PREPARA UNA SISTEMA DE DOBLE FASE LIQUIDA PARA UNA SOLUCION ACUOSA CONCENTRADA DE UN SOLUBLE Y UNA SOLUCION DEL POLIMERO EN UN SOLVENTE ORGANICO QUE ES AL MENOS PARCIALMENTE MEZCLABLE CON EL AGUA, Y ENTONCES SE AÑADE AGUA HASTA QUE TODO EL SOLVENTE ORGANICO SE HA DIFUNDIDO POR EL INTERIOR DE LA FASE ACUOSA. LAS MICROPARTICULAS DEL POLIMERO SE LAVAN Y SE SECAN ENTONCES. CUANDO SE VUELVEN A SUSPENDER EN AGUA, SE CONVIERTEN EN PSEUDO LATEX.
