PolyAMPS, or poly(2-acrylamido-2-methyl-1-propanesulfonic acid), is an organic polymer. It is water-soluble, forms gels when cross linked, and acts as an anionic polyelectrolyte. It can be used for ion exchange resins. It can form hydrogels. Jump to: navigation, search A polymer is a generic term used to describe a substantially long molecule. ... A gel (from the lat. ... Vulcanization is an example of cross-linking. ... Polyelectrolytes combine the properties of electrolytes (salts) and polymers (high MW compounds). ... An ion exchange resin is an insoluble matrix (or support structure) normally in the form of small (1-2mm diameter) beads, fabricated from an organic polymer substrate on the surface of which are sites with easily trapped and released ions in a process called ion exchange. ...
