Characterization of a superabsorbent polymer
Journal of Applied Polymer Science, 2007AbstractWe studied an amorphous polymer superabsorbent, able to absorb until 1000 times its weight of water. It is consisted of macromolecular chains, dependent between them by chemical bonds. The swelling of the product in the presence of water gives rise to a polyelectrolytic gel. The chemical analysis of polymer by energy dispersive spectrometry and

Biodegradation of superabsorbent polymers in soil
Environmental Science and Pollution Research, 2000Biodegradation of two superabsorbent polymers, a crosslinked, insoluble polyacrylate and an insoluble polyacrylate/ polyacrylamide copolymer, in soil by the white-rot fungus, Phanerochaete chrysosporium was investigated. The polymers were both solubilized and mineralized by the fungus but solubilization and mineralization of the copolymer was much more

Acrylamide–itaconic acid superabsorbent polymers and superabsorbent polymer/mica nanocomposites
Polymers for Advanced Technologies, 2011AbstractSuperabsorbent polymer acrylamide (AM)/itaconic acid (IA) and its nanocomposite were synthesized by redox polymerization in an aqueous solution of both monomers with mica used as an inorganic additive. The influences of IA concentration, mica content, and crosslinker concentration on the water absorption and physical properties of the ...

The Synthesis of a Superabsorbent Polymer
Journal of Chemical Education, 1997The preparation and mode of action of a superabsorbent polymer is described. The material consists of lightly crosslinked, mostly neutralized polyacrylic acid which can be prepared using either a redox or a thermal radical initiator. The resulting polymer absorbs 500-3000 times its weight in distilled water, depending on the degree of crosslinking ...

AbstractThe desired performance characteristics of absorbent products such as diapers include a low number of leaks, adequate liquid absorption capacity, and high skin dryness. By measuring the absorption behavior of mixtures of cellulose fluff pulp and superabsorbent polymers in nonimmersed conditions, we identify four major parameters that affect the

Superabsorbent polymers (SAPs) are able to absorb up to 1500 g of water per gram of SAP. Chemically speaking, SAPs are cross-linked polyelectrolytes which start to swell upon contact with water or aqueous solutions resulting in the formation of a hydrogel.
