Polyacrylamide CAS No.: 9003-05-8
Polyacrylamide CAS No.: 9003-05-8 is a polymer (-CH2CHCONH2-) formed from acrylamide subunits.One of the largest uses for polyacrylamide is to flocculate solids in a liquid.This process applies to water treatment, and processes like paper making and screen printing.Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer.Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other chemical species, such as an acrylic acid or a salt thereof.The main consequence of this is to give the 'modified' polymer a particular ionic character.
