• soluble means at least about 0.1 g of solute dissolves in 100 ml of solvent, at 25° C. and 1 atm of pressure.
• superabsorbent polymer is understood to mean a polymer which is capable, in its dry state, of spontaneously absorbing at least 20 times its own weight of aqueous fluid, in particular of water and especially of distilled water.
• SAP superabsorbent polymer
• These polymers have a high capacity for absorbing and retaining water and aqueous fluids. After absorption of the aqueous liquid, the particles of the polymer thus impregnated with aqueous fluid remain insoluble in the aqueous fluid and thus retain their separated particulate state.
• Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (sometimes referred to as sodium polyacrylate).
• This polymer is the most common type of superabsorbent polymers made in the world today.
• Other materials are also used to make a superabsorbent polymer, such as polyacrylamide copolymer, ethylene maleic anhydride copolymer, cross-linked carboxymethylcellulose, polyvinyl alcohol copolymers, cross-linked polyethylene oxide, and starch grafted copolymer of polyacrylonitrile to name a few. The latter is one of the oldest superabsorbent polymers forms created.
• Today superabsorbent polymers are made using one of three primary methods; gel, polymerization, suspension polymerization or solution polymerization.
• Gel Polymerization involves a mixture of frozen acrylic acid, water, cross-linking agents and UV initiator chemicals are blended and placed either on a moving belt or in large tubs.
• the liquid mixture then goes into a “reactor” which is a long chamber with a series of strong UV lights.
• the UV radiation drives the polymerization and cross-linking reactions.
• the resulting “logs” are sticky gels containing 60-70% water.
• the logs are shredded or ground and placed in various sorts of driers.
• Additional cross-linking agent may be sprayed on the particles' surface; this “surface cross-linking” increases the product's ability to swell under pressure—a property measured as Absorbency Under Load (AUL) or Absorbency against Pressure (AAP).
• AUL Absorbency Under Load
• AAP Absorbency against Pressure
• the dried polymer particles are then screened for proper particle size distribution and packaging.
• the Gel Polymerization (GP) method is currently the most popular method for making the
• Solution polymers those made by solution polymerization, offer the absorbency of a granular polymer supplied in solution form.
• the solution polymers can be diluted with water prior to application and coat most substrates or used saturated. After drying at a specific temperature for a specific time, the result is a coated substrate with superabsorbent functionality.
• this chemistry can be applied directly onto wires & cables, though it is especially optimized for use on components such as rolled goods or sheeted substrates.
• Solution based polymerization is commonly used today for SAP manufacture of co-polymers—particularly those with the toxic acrylamide monomer. This process is efficient and generally has a lower capital cost base.
• the solution process uses a water based monomer solution to produce a mass of reactant polymerized gel.
• the polymerization's own reaction energy is used to drive much of the process, helping reduce manufacturing cost.
• the reactant polymer gel is then chopped, dried and ground to its final granule size. Any treatments to enhance performance characteristics of the SAP are usually accomplished after the final granule size is created.
• Superabsorbent polymers can also be made by suspension polymerization. This process suspends the water-based reactant in a hydrocarbon-based solvent. The net result is that the suspension polymerization creates the primary polymer particle in the reactor rather than mechanically in post-reaction stages. Performance enhancements can also be made during, or just after, the reaction stage.
• the superabsorbent polymer can have a water-absorbing capacity ranging from 20 to 2000 times its own weight (i.e., 20 g to 2000 g of water absorbed per gram of absorbent polymer), from 30 to 1500 times and also ranging from 50 to 1000 times, and about 400 times. These water-absorbing characteristics are defined at standard temperature (25° C.) and pressure (760 mm Hg, i.e. 100 000 Pa) conditions and for distilled water.
• the value of the water-absorbing capacity of a polymer can be determined by dispersing 0.5 g of polymer(s) in 150 g of a water solution, by waiting 20 minutes, by filtering the nonabsorbed solution through a 150 nm filter for 20 minutes and by weighing the nonabsorbed water.
• the superabsorbent polymer used in the composition of the invention can be provided in the form of particles which, once hydrated, swell with the formation of soft beads having a number-average diameter of about 10 nm to about 1000 nm.
