ABSTRACT:
The present invention involves compositions of super absorbent polymers which absorb many times their weight in water and aqueous fluids. Super absorbent polymers in the prior art have effectively absorbed many times their weight of water, however, they become slimy to the touch or become so fluid as to migrate away from their point of application.
The absorbent composition of the current invention absorbs substantial amounts of water without becoming slimy and migrating out from its applicator, as in absorbent articles. The absorbent composition of the current invention comprises a copolymer of acrylic acid cross-linked with a first cross-linking component comprising a monomer having at least two vinyl groups and a second cross-linking component comprising an ionic divalent cation. In the current invention, this composition can be mixed with cellulose fibers to enhance wicking. This composition is useful in absorbent articles and has proven to be particularly well suited to be incorporated between two plies of paper to make a two-ply paper towel.
