Abstract
The invention relates to a superabsorbent copolymer comprising a reaction product of a reactive optical brightener comonomer. In another embodiment, the superabsorbent copolymer comprises a reaction product of a first monomer and a reactive optical brightener comonomer. The reactive optical brightener comonomer may be selected from various pyrene optical brighteners listed herein. The invention also relates to superabsorbent copolymer having from about 0.1 to 10,000 ppm of a reactive optical brightener comonomer based on the superabsorbent copolymer.

A superabsorbent copolymer comprising a reaction product of a reactive optical brightener comonomer.
A superabsorbent copolymer comprising a reaction product of a first monomer and a reactive optical brightener comonomer.
A superabsorbent copolymer comprising a reaction product of a first monomer and a reactive optical brightener comonomer wherein the reactive optical brightener comonomer reacts with the first monomer to form network polymer chains in the superabsorbent copolymer wherein the reactive optical brightener comonomer is incorporated into the network polymer chains of the superabsorbent copolymer.
