Polyacrylamide for Best Price

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide. In the cross-linked form, the possibility of the monomer being present is reduced even further.

Fungi also have the ability to decompose PAM. Stahl et al. investigated the biodegradation of two superabsorbent polymers (namely a crosslinked, insoluble polyacrylate and an insoluble polyacrylate/polyacrylamide copolymer) in soil by the white-rot fungus Phanerochaete chrysosporium. The polymers were both solubilized and mineralized by the fungus but solubilization and mineralization of the copolymer was much more rapid than that of the polyacrylate.

Synthesis of polyacrylamide with pendant poly(n‐octyl

An amphiphilic graft copolymer of polyacrylamide (PAM) with uniform poly(n‐octyl acrylate) (POA) grafts was synthesized by copolymerization of AM with POA macromer in solution using azobisisobutyronitrile as the initiator. The macromer was synthesized by free radical polymerization of octyl acrylate in the presence of different amounts of thioglycolic acid as the chain transfer agent, followed by termination with glycidyl methacrylate.

Formation and structure of polyacrylamide gels

Polyacrylamide (PAAm) gels are obtained by free- radical crosslinking copolymerization of acrylamide (AAm) and N,N-methylenebis(acry1amide) (Bis) monomers. Since the monomers are solid at the usual polymerization temperature, it is necessary to carry out the polymerization reactions in an aqueous * To whom correspondence should be addressed.

Using Polyacrylamide (PAM) to Reduce Erosion on Construction

PAM is water soluble, but dissolves very slowly and requires rapid agitation and extended mixing time. Water with more than 0.1 percent dissolved PAM is often noticeably viscous, and most PAMs have a maximum concentration of 0.5 to 1 percent in water. A good rule of thumb is to mix 1 pound of PAM per 100 gallons of water.
