Abstract

Patente de Invenção: <B>"RESINA HIDROFìLICA, ARTIGO ABSORVENTE, E áCIDO ACRìLICO PARA POLIMERIZAçãO"<D>. A presente invenção fornece uma resina hidrofílica e um artigo absorvente, ambos os quais exibem ainda menos coloração e descoloração quando coservados durante um longo tempo. A resina hidrofílica é qualquer uma de: 1) uma resina hidrofílica, obtida por um processo incluindo a etapa de polimerização de um componente de monómero incluindo uma maior proporção ou um ou ambos os ácidos acrílicos e seus sais que simplesmente têm um conteúdo de no máximo 0,20 ppm, em todal de hidroquinona e benzoquinona; 2) uma resina hidrofílica, compreendendo uma maior proporção de um pilímero acrílico e uma menor proporção de ou um ou ambos hidroquinona e benzoquinona, com a resina hidrofílica ainda compreendendo um inibidor de quinhidronação de 10 a 1.000.000 vezes o peso total de hidroquinona e benzoquinona; 3) uma resina hidrofílica, compreendendo uma maior proporção de um polímero acrílico e simplesmente tendo um grau de coloração (YI) de no máximo 20 após ser deixado sob condições do sistema aberto, 70°C, 65% de UR durante uma semana; e 4) uma resina hidrofílica, que é uma resina absorvente de água e é de superfície reticulda ou superfície impregnada com um álcool polihídrico e exibe um pH de 5,5 ou menos em uma solução fisiológica de sal e tem uma capacidade de absorção de 20 g/g ou mais para uma solução fisiológica de sal sob um carga de 50 g/cm³. Além disso, um artigo absorvente compreende a resina hidrofílica acima mencionada.
