Disclosed is an absorbent composition comprising each of an acidic and a basic material, wherein the absorbent composition exhibits desirable absorbent properties. Specifically, the present invention relates to an absorbent composition comprising either an acidic water-swellable, water-insoluble polymer having a pKa between about 2 to about 12 or a basic water-swellable, water-insoluble polymer having a pKb between about 2 to about 12 and either a basic or an acidic second material. The absorbent composition has the ability to slowly absorb a large quantity of liquid, particularly while under an external pressure. The absorbent composition is useful in disposable absorbent products, such as those disposable absorbent products that are used to absorb bodily liquids.
