Polyacrylamide (abbr. PAA) — the general name of group of polymers and copolymers on the basis of acrylamide and its derivatives.
Constitutional repeating unit of macromolecule of polyacrylamide
By rules IYuPAK weed the main name (2 propenamide) or weed (1 - karbamoiletilen), the general formula ( - CH2CHCONH2 - ) n
Application
Polyacrylamide finds the main application as inexpensive water soluble polymer with properties of polyelectrolyte. The main scopes of PAA are included below:
Water treatment. PAA — good and inexpensive coagulant and flocculant for purification of drinking water, technology drain waters.
Receiving gels for chemical analysis of complex biological systems.
In production of mineral fertilizers
In molecular biology of PAA gel electrophoresis of proteins and nucleic acids is used as the supporting environment for carrying out (so - called. PAAG - electrophoresis) [1][2]
Use in oil industry for flooding of layers and carrying out repair and insulating works in well
Polyacrylamide is used in boring solutions at oil production as the regulator of water return and negative catalyst of swelling of clay.
