Abstract

ESTE INVENTO RELATA A PROCESOS DE POLIMERIZACION DE SUSPENSION, PARA CADENAS POLIMERICAS QUE ABSORVEN FLUIDOS ACUOSOS PRODUCIDOS DE ESOS PROCESOS, PARA SUSPENDER AGENTES EMPLEADOS EN DICHOS PROCESOS Y A UN METODO DE USAR AGENTES HUMEDECEDORES PARA MEJORAR LA PROPORCION DE HIDRATACION DE LAS CADENAS POLIMERICAS ABSORVENTES DE FLUIDO ACUOSO. LOS AGENTES HUMEDECEDORES TALES COMO POLIOLS QUE NO REALICEN LA TENSION SUPERFICIAL DE UN SUPERNATE (PROVISTO POR METODO DE TEST STANDARD) ABAJO DE 56 DINAS/CM PUEDE MEJORAR LA PROPORCION DE HIDRATACION DE UNA CADENA POLIMERICA ABSORVENTE DE FLUIDO ACUOSO, PRODUCIDO POR UN PROCESO DE POLIMERIZACION DE SUSPENSION. EL AGENTE HUMEDECEDOR ES UTIL EN UN PROCESO DE POLIMERIZACION DE SUSPENSION ACEITE EN AGUA EN DONDE EL AGENTE SUSPENSOR COMPRENDE UNA PARTICULA SILICE AHUMADA QUE TIENE UN CARACTER HIDROFOBICO Y UN POLIMERO HIDROFOBICO.
