Abstract: The invention relates an absorbent article and a process for making an absorbent article. The absorbent article comprises an acquisition and distribution system comprising at least one acquisition and/or distribution layer comprising one or more saturated carboxylic acids. The one or more saturated carboxylic acids are each selected from the group of monocarboxylic acids, dicarboxylic acids or tricarboxylic acids. The one or more saturated carboxylic acids each have a pKa for the first acid dissociation in water and the pKa of each carboxylic acid is from 2.5 to 5.0.

Abstract: A method of making superabsorbent polymer material and comprising the step of providing soluble polyacrylic acid polymers. The soluble polyacrylic acid polymers have a molar percent of carbon-to-carbon double bonds of at least 0.03. The soluble polyacrylic acid polymers may be obtained from pre-existing recycled post-consumer superabsorbent polymer material, and/or from pre-existing recycled post-industrial superabsorbent polymer material. Superabsorbent polymer material obtained by the method, and absorbent articles comprising these materials are also provided.

Abstract: A monomer composition for preparing superabsorbent polymer is presented. The superabsorbent polymer is subsequently incorporated into an absorbent article. The monomer composition for preparing the superabsorbent polymer of the present disclosure has rapid polymerization speed and thus can minimize bubble loss during blowing polymerization, therefore it can provide superabsorbent polymer having excellent absorption speed. The superabsorbent polymer prepared from the monomer composition for preparing superabsorbent polymer has high gel strength and thus maintains its shape well even after moisture absorption, thus it may exhibit excellent absorption performance in spite of external pressure.
