Abstract

DISPERSIONES DE PARTICULAS DE POLIACRILAMIDA DE ELEVADO PESO MOLECULAR FINAMENTE DIVIDIDAS SE FORMAN Y TRATAN CON UN MATERIAL CAUSTICO PARA HIDROLIZAR EL POLIMERO SIN REACCIONES LATERALES EN CADENA INDESEABLES PARA FORMAR POLIMEROS ACRILAMIDA ANIONICOS DE ELEVADO PESO MOLECULAR. UNA TECNICA PREFERIDA PARA FORMAR ESTOS PRODUCTOS COMPRENDE LA FORMACION DE UNA EMULSION ESTABILIZADA DE ACEITE EN AGUA DE MONOMERO ACRILAMIDA, POLIMERIZAR EL MONOMERO, REACCIONAR LA EMULSION POLIMERA ASI FORMADA CON UN AGENTE DE HIDROLISIS E INVERTIR LOS POLIMEROS RESULTANTES HIDROLIZADOS EN LA DISOLUCION. ESTOS MATERIALES SE USAN EN UNA VARIEDAD DE APLICACIONES INDUSTRIALES PARA ELIMINAR PARTICULAS FORMADAS A PARTIR DE CORRIENTES EMANADAS.
