Abstract
a presente invenção refere-se a um polímero superabsorvente que exibe uma permeabilidade ao líquido mais aperfeiçoada, mantendo um excelente desempenho de absorção e suprime a agregação e aglutinação de partículas mesmo sob condições de alta temperatura/alta umidade, e a um método para produzir o mesmo. o polímero superabsorvente compreende: um pó de polímero base incluindo um primeiro polímero reticulado de um monômero etilenicamente insaturado solúvel em água tendo, pelo menos, parcialmente grupos acídicos neutralizados; e uma camada reticulada da superfície formada sobre o pó de polímero base e incluindo um segundo polímero reticulado, em que o primeiro polímero reticulado é ainda reticulado através de um agente de reticulação da superfície, em que o polímero superabsorvente inclui sulfato de alumínio disperso na camada reticulada da superfície e alumina dispersa sobre a camada reticulada da superfície.
