Abstract
AGENTE DE ABSORçãO DE AGUA, ARTIGO PARA ABSORçãO DE áGUA E MéTODO PARA A PRODUçãO DE UM AGENTE DE ABSORçãO DE áGUA. Um objeto da presente invenção compreende proporcionar um agente de absorção de água que possui uma pequena quantidade de monâmero residual, uma pequena varlância da quantidade de monómero residual entre as faixas de distribuição de tamanho de partícula e propriedades de absorção favoráveis e de características sanitárias; um artigo absorvente; e um método para a produção de um agente de absorção de água. O agente de absorção de água da presente invenção possui uma quantidade de monómero residual que não é superior a 500ppm, e um índice de monómero residual que não é maior do que 0,30. O método para produção inclui uma primeira etapa de obtenção do polímero hidrogel para polimerização de uma solução aquosa de um monómero que inclui um ácido carboxílico insaturado e/ou um sal do referido ácido na presença de um agente de reticulação; uma segunda etapa de obtenção de um precursor de uma resina de absorção de água que está na forma de pó e inclui partículas que possuem um tamanho de partícula de 300 a 850 <sym>m e partículas que possuem um tamanho de partícula menor do que 300<sym>m como componentes principais por meio de secagem do polimero hidrogel seguida de pulverização e classificação para ajustar a distribuição de tamanho de partícula, uma terceira etapa para obtenção de uma resina de absorção de água por meio de aquecimento de uma mistura do precursor da resina de absorção de água e um agente reticulador de superfície que pode formar uma ligação éster ao redor da superfície do precursor da resina de absorção de água, uma quarta etapa em que é su}netida a mistura da resina de absorção de água e a solução aquosa a um tratamento térmico sob um fluxo de ar não inferior a 40°C, mas não superior a 120°C.
