Abstract

PARA LA PREPARACION DE POLVOS SUPERABSORBENTES CONSTITUIDOS POR ACIDO POLIACRILICO PARCIALMENTE NEUTRALIZADO, SEGUN UN PROCESO QUE COMPRENDE LA FORMACION DE UN GEL POLIMERO POR UNA PRIMERA POLIMERIZACION DE MONOMERO EN SUSPENSION INVERSA SEGUIDA DE LA POLIMERIZACION DE UNA SEGUNDA CARGA DE MONOMERO ABSORBIDA EN EL GEL 1 SE UTILIZA SUCESIVAMENTE UNAS CARGAS DE ACIDO ACRILICO MONOMERO RESPECTIVAMENTE SOBRE NEUTRALIZADO Y SUBNEUTRALIZADO EN RELACION A LA TASA DE NEUTRALIZACION DEL POLIMERO FINAL. LOS POLVOS ASI OBTENIDOS ESTAN CONSTITUIDOS POR PARTICULAS DE FORMA ESFEROIDALES. ES MUY VENTAJOSO CONDUCIR EL PROCESO CON LA AYUDA DE EMULSIFICANTES CONVENIENTEMENTE ESCOGIDOS PARA QUE LA FASE DE ABSORCION DE MONOMERO POR EL GEL INTERMEDIO PUEDA SER EJECUTADA A UNA TEMPERATURAS DEL ORDEN DE 35-45 C.
