PROCESS FOR MAKING A MULTIFUNCTIONAL SUPERABSORBENT POLYMER

摘要

A process for making a multifunctional superabsorbent polymer, and for making an absorbent structure containing superabsorbent polymer. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the multifunctional superabsorbent polymer and/or absorbent structure. More particularly, a monomer solution containing an oxidizing agent, a monomer solution containing a reducing agent, and at least one functional additive are combined to form the multifunctional superabsorbent polymer. A valve can be used to control the liquid drop sizes of the monomer solutions as well as of the oxidizing agent, reducing agent, and functional additive(s). The droplets can be collected on a substrate, resulting in the formation of an absorbent structure.
