Polyacrylamide (PAM) /nonionic polyacrylamide/cation polyacrylamide/anionic polyacrylamide, alias flocculant Nke 3, bụ polima kwụ ọtọ nke mmiri na-agbaze site na polymerization free radical nke acrylamide (AM) monomer. Usoro njikọta na flocculation na ọgwụgwọ mmiri, Polyacrylamide sds nwere ezigbo flocculation ma nwee ike ibelata esemokwu dị n'etiti mmiri mmiri. Enwere ike kewaa iguzogide n'ime ụdị anọ: anionic, cationic, nonionic na amphoteric dịka njirimara ionic si dị.
Polyacrylamide bụ ihe ntụ ntụ ọcha, nke enwere ike ịgbaze na mmiri n'ogo ọ bụla, ihe ngwọta mmiri ahụ dị otu ma doo anya, oke nke ihe ngwọta mmiri ahụ na-abawanye nke ukwuu ka ibu molekul nke polima ahụ na-abawanye. PAM anaghị agbaze na ọtụtụ ihe mgbaze organic, dịka formaldehyde, ethanol, acetone, ether, wdg.
Polyacrylamide bụ kemịkalụ mmiri nke a na-agbaze na mmiri ma ọ bụ polyelectrolyte.
