Abstract

PARA LA PREPARACION DE POLVOS POLIACRILICOS SUPERABSORBENTES PARA EL AGUA Y LOS LIQUIDOS ACUOSOS POR POLIMERIZACION EN SUSPENSION INVERSA QUE PROCEDE SEGUN 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 ABSORBIDO EN EL GEL, SE UTILIZA UNOS TENSIOACTIVOS POLIMERIZABLES QUE RESPONDEN A LA FORMULA: R1 O)N ATOMOS DE CARBONO Y R2, UNA AGRUPACION POLIMERIZABLE, RESIDUO ACRILOILO, METACRILOILO O MALEOILO. LA ABSORCION DEL MONOMERO POR EL GEL PUEDE HACERSE A UNAS TEMPERATURAS INICIALES DEL GEL DE 45 C. RESULTA UNA VENTAJA CONSIDERABLE EN CUANTO A LA DIRECCION Y A LA ECONOMIA DEL PROCESO.
