[ Properties ]
Polyacrylamide, abbreviation PAM,is a glassy solid, easy to adsorb water ; the absorbing speed are varied with different derivative ions.Polyacrylamide is soluble in water and organic solvents as acetic acid, glycol, glycerin and amine. Polyacrylamide will be decomposed after long time heating. Decomposed temperature is over 200oC. Polyacrylamide can be carbonated into black powder at 210οC without oxygen.
Polyacrylamide could be made to four series,e.g., non-ion polyacrylamide, cationic polyacrylamide CPAM , anionic polyacrylamide APAM and zwitterionic polyacrylamide.
[ Uses ]
Polyacrylamide is an important water-soluble compound with the properties of flocculation, thickening, cut-resisting, block-reducing dispersing, etc .These properties are varied with different derivative ions.So polyacrylamide is widely used in the field of oil extraction, mining selection, coat washing, metallurgy, chemical, papermaking, sugar refining, pharmaceutical, environment protection, construction materials and agriculture.
