Polyacrylamide bụ polymer linear, a na-ekewa ngwaahịa ahụ n'ime ntụ ntụ na colloidal abụọ. Dị ka nkezi molecular arọ ya si dị, enwere ike kewaa ya n'ime obere molecular arọ (<1 million), ọkara molecular arọ (2 ~ 4 million) na elu molecular arọ (> .7 nde) .Dịka usoro ya nwere ike kewaa n'ime ndị na-abụghị. - cationic, ion na ion. Mgbasa mmiri (HPAM) nke ụdị anion. Isi yinye nke polyacrylamide nwere ọnụ ọgụgụ dị ukwuu nke amide, nwere ọrụ kemịkal dị elu, enwere ike gbanwee ya iji mepụta ọtụtụ ihe nrụpụta nke polyacrylamide. A na-eji ngwaahịa ndị ahụ eme ihe n'ọtụtụ ebe n'ịkpụ akwụkwọ, nhazi ịnweta, mpụta mmanụ, metallurgy, ihe ụlọ, ọgwụgwọ nsị na ụlọ ọrụ ndị ọzọ.
