Method of making an absorbent structure having high integrity

A method of making an absorbent structure, comprising the steps of:

• providing a fibrous web substrate including about 25 to about 100% by weight hydrophilic fibers and zero to about 75% by weight thermoplastic fibers;
• adding a first superabsorbent polymer precursor composition including ay least a monomer to the fibrous web at a plurality of discrete, spaced-apart locations;
• adding a second superabsorbent polymer precursor composition including at least a monomer to the fibrous web at the plurality of discrete, spaced-apart locations;
• and
• chemically reacting the first and second superabsorbent polymer precursor compositions at the plurality of locations to form a plurality of discrete, spaced-apart microdomains of superabsorbent polymer adhering to the fibrous web;
• wherein the first and second superabsorbant polymer precurser compositions are not combined with each other before being added to the fibrous web.

A method of making an absorbent structure, comprising the steps of:

• providing a first superabsorbent polymer precursor composition including a monomer, a crosslinking agent and a reducing agent;
• providing a second superabsorbent polymer precursor composition including a monomer, a crosslinking agent and an oxidizing agent;
• and
• chemically reacting the first and second superabsorbent polymer precursor compositions at a plurality of spaced-apart locations on or in a substrate to provide a plurality of discrete, spaced-apart microdomains of superabsorbent polymer adhered to the substrate;
• wherein the first and second superabsorbant polymer precurser compositions are not combined with each other apart from the substrate.
