发明名称 POLYMER MIXTURE OF HYDROGELS WITH DIFFERENT PH VALUE
摘要 The invention relates to polymeric mixtures containing hydrogel-forming polymers with different pH values and which absorb aqueous fluids. Said polymeric mixtures can be produced by polymerization of olefinically unsaturated carboxylic acids or derivatives thereof. The invention also relates to the production and use of said polymeric mixtures and to the hygienic articles containing said polymeric mixtures. The invention particularly relates to two-component polymeric mixtures from polymers with a pH range from acid to neutral.
