Because of it's excellent performance and low cost, Anionic polyacrylamide(APAM) are widely used in the domain of water treatment,however,China's technology of APAM are not mature,the intention of this thesis is synthesize a kind of APAM with high intrinsic viscosity and no pollution.
Dispersion copolymerization of acrylamide(AM)and acrylic acid (AA)has been carried out in aqueous solution of ammonium sulfate(AS), using polyvinyl pyrrolidone(PVP) as stabilizer. Anionic polyacrylamide(APAM) was prepared....
