Abstract

"PARTìCULA DE RESINA ABSORVENTE E ABSORVENTE E PARTìCULA ABSORVENTE EMPREGANDO A MESMA". Uma partícula de resina absorvente compreendendo um polímero reticulado (A) e uma substância hidrofóbica (C), o polímero reticulado (A) incluindo, como unidades constituintes essenciais, um monómero de vinila solúvel em água (a1), e/ou um monómero de vinila (a2) que é formado no monómero de vinila solúvel em água (a1) por hidrólise, e um agente de reticulação interna (b), é fornecida, onde a partícula de resina absorvente tem uma estrutura tal que uma parte ou um todo da substância hidrofóbica (C) esteja contida no interior de cada partícula da partícula de resina absorvente. Além disso, um absorvente e um artigo absorvente no qual a partícula de resina absorvente anterior é empregada são fornecidos também. é possível fornecer a partícula de resina absorvente aplicável para formar um artigo absorvente que exibe um alto desempenho de absorção (quantidade de absorção e taxa de absorção) sob qualquer condição e é substancialmente livre de vazamento, e um absorvente bem como um artigo absorvente no qual sua partícula de resina absorvente é empregada.
