These ions attract water into the polymer by diffusion. The polymer absorbs water within a few seconds to form slush. Due to its rapid and large water-absorbency (and its harmlessness), sodium polyacrylate is used as the absorbent material in diapers. Polyacrylamide consists of repeating units of the monomer –CH 2 CH(CONH 2)–. The nitrogen
Absorbent polymer resin, is non-toxic polymer network polymer, a strong water absorption. Use (1) Health: sanitary napkins, changing mat, diapers, medical mattresses, absorbent paper, sustained-release drug, cream, water bag and so on. (2) Agriculture and Forestry: Soil water retention, seed coating, seed dressing nursery.
PAM copolymers used as retention aids have molecular masses in the range 2 to 15 million g/mole, and many of them are delivered as water-in-oil emulsions. PAM copolymers used as dry-strength resins are usually solution copolymers (no oil present) with molecular masses up to 1 million g/mole.
Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the capture of dispersed bacterial cells, suspended solids, and cell fragments; therefore, one of its
The hydrated PAM is a softthat is used inelectrophoresis and as a super water-absorbing polymer (SAP's). Even though these polymers are called polyacrylamide, they are often copolymers of acrylamide and one or more other monomers. The most important co-monomer is acrylic acid or sodiumacrylate.
A leading professional manufacturer of polyacrylamide (PAM) and super absorbent polymer (SAP) in China. The capacity reaches 100,000 tons/year for PAM including the full range cationic, anionic non ionic powders emulsions. SAP is 150,000 tons/year. Our
Added by: snoofer . Contributed by: Snoozer What are polymers and what are water-absorbent polymers? A polymer is a string of repeating molecules that forms along chain. DNA is a polymer, as are starches, proteins, etc. Forexample, casein - the protein that makes cow's milk - is a polymer.About 30 years ago the plastics industry was looking to change thenegative image people have of the word
superabsorbent polyacrylate polymer (SAP) used in diapers is a cross-linked polymer regarded as relatively safe, but it would be wise to wear gloves when handling the polymer and to ensure good ventilation. The other polymer mentioned in that article, sodium polyacrylate, may be much more hazardous than the diaper SAP. 6 CHEM 13 NEWS/May 2007

Best quality of super absorbent polymer (sap)from Chinafloc Chinafloc-sap is a highly efficient polymer based water retainer that, when incorporated into a soil or a substrate will absorb and retain large quantities of water and nutrients.
Polyacrylamide is used in the preparation of acrylamide gels for separation of proteins. Packaging 10, 50 g in glass bottle Biochem/physiol Actions Polyacrylamide is a water-soluble polymer made up of acrylamide subunits. It increases the viscosity of water and facilitates the flocculation of particles present in water.
Polyacrylate, any of a number of synthetic resins produced by the polymerization of acrylic esters.Forming plastic materials of notable clarity and flexibility under certain methods, the polyacrylates are employed primarily in paints and other surface coatings, in adhesives, and in textiles. The most common polyacrylates are polyethyl acrylate and polymethyl acrylate.

The origins of superabsorbent polymer chemistry trace back to the early 1960s when the U.S. Department of Agriculture developed the first super absorbent polymer materials. As a function polymer material, superabsorbent polymer (SAP) has strong water absorbing ability. It can absorb hundreds times its weight and lock water firmly.
Copolymers and polymer blends. When a single monomer is polymerized into a macromolecule, the product is called a homopolymer—as shown in Figure 3A, with polyvinyl chloride as the example. Copolymers, on the other hand, are made from two or more monomers.Procedures have been developed to make copolymers in which the repeating units are distributed randomly (Figure 3B), in alternating fashion
