Abstract

no que diz respeito a resinas absorventes de água, são proporcionados um método de fabricação de uma resina absorvente de água que possui uma superfície específica bet apropriada e uma taxa de absorção de água e um agente absorvente de água e um artigo absorvente que são formados usando a resina absorvente de água. em um primeiro aspecto da presente invenção, quando a polimerização em suspensão de fase reversa de duas ou mais etapas é realizada em um monômero etilenicamente insaturado solúvel em água em um meio de dispersão de hidrocarboneto na presença de pelo menos um composto azo, um peróxido e um agente de reticulação interna, a quantidade utilizada de agente de reticulação interna no momento da polimerização de uma primeira etapa é ajustada para cair no intervalo de 0,015 a 0,150 mmol por mol de o monômero etilenicamente insaturado solúvel em água utilizado no momento da polimerização da primeira etapa e a polimerização é realizada de tal modo que a área de superfície bet específica das partículas secundárias formadas por aglomeração de partículas primárias obtidas é controlada.
