Abstract

"MéTODO PARA A PRODUçãO DE RESINA ABSORVENTE DE áGUA". Um processo para preparar uma resina absorvente de água compreendendo a execução de polimerização de uma suspensão em fase reversa em etapas múltiplas de pelo menos duas etapas quando a resina absorvente de água e preparada por submeter uma monómero etilênicamente são saturado solúvel em água á polimerização de suspensão em fase reversa, o referido processo para a preparação de uma resina absorvente de água sendo caracterizado pela adição<39> de um composto contendo fósforo a, pelo menos, uma etapa na segunda etapa e etapas subseqüentes, para a execução da reação de polimerização. A resina absorvente de água pode ser usada adequadamente m materiais higiênicos tais como fraldas descartáveis, coxins para incontinência e quardanapos higiênicos, especialmente em fraldas descartáveis.
