Abstract

resumo “método de preparação de polímero superabsorvente” a presente invenção refere-se a um método de preparação de um polímero superabsorvente (sap). o método de preparação para sap de acordo com a presente invenção inclui: a preparação de um primeiro polímero pela realização de uma polimerização térmica ou fotopolimerização de uma composição de monômero compreendendo um monômero insaturado com base em etileno solúvel em água e um iniciador de polimerização; a preparação de um segundo polímero pela realização de uma polimerização térmica ou fotopolimerização de uma composição de monômero compreendendo um monômero insaturado com base em etileno solúvel em água e um iniciador de polimerização; secagem do primeiro polímero; a moagem do primeiro polímero seco; e a mistura do primeiro polímero moído com o segundo polímero no estado livre de intumescimento usando a solução de reticulação para causar uma reação de reticulação dos primeiro e segundo polímeros. de acordo com a presente invenção, é possível obter um polímero superabsorvente (sap) tendo alta capacidade de retenção da centrífuga e alta absorção sob pressão.
