Abstract

EL POLIMERO EN POLVO SEGUN LA INVENCION A BASE DE AL ENOS UN MONOMERO HIDROSOLUBLE ETILENICAMENTE INSATURADO, POSEE UNA CAPACIDAD DE SUCCION CAPILAR BAJO PRESION DESPUES DE 20 MINUTOS AL MENOS IGUAL A 28 ML/G. ESTE POLIMEOR PUEDE PREPARARSE POR UN PROCEDIMIENTO QUE CONSISTE EN DISPERSAR Y PONER EN SUSPENSION UNA FASE ACUOSA (1) CONSTITUIDA POR UNA SOLUCION ACUOSA DE AL MENOS UN MONOMERO HIDROSOLUBLE ETILENICAMENTE INSATURADO, CONTENIENDO UNA CANTIDAD EFICAZ DE AL MENOS UN AGENTE DE RETICULACION SOLUBLE EN DICHA FASE (1), EN UNA FASE OLEOSA (2) CONSTITUIDA POR AL MENOS UN HIDROCARBURO LIFATICO O ALICICLICO, TENIENDO AL MENOS 6 ATOMOS DE CARBONO Y CONTENIENDO UNA CANTIDAD EFICAZ DE AL MENOS UN AGENTE TENSOACTIVO, DESPUES DE POLIMERIZAR DICHO MONOMERO HIDROSOLUBLE ETILENICAMENTE INSATURADO EN PRESENCIA DE AL MENOS UN GENERADOS DE RADICALES LIBRES, EL AGENTE TENSIOACTIVO ESTA ELEGIDO DE MANERA QUE PUEDA EFECTUAR LA POLIMERIZACION CON UN CONTENIDO EN PESO DE LA DASE (2) A LA FASE (1) INFERIOR O IGUAL A 0,75. APLICACION A LA OBTENCION DE ARTICULOS CAPACES DE ABSORBER LOS FLUIDOS ACUOSOS, PARTICULARMENTE EN EL CAMPO DE LA HIGIENE Y DE LA AGRICULTURA.
