Polyacrylamide (PAM)
CAS No.:
9003-05-8
Molecular Formula:
(C3H5NO)n
Structure Formula:
Properties:
Polyacrylamide, abbreviation PAM, is a glassy solid, apt to water absorption. Polyacrylamide is the speed of absorbing water that varies with different derivative ions.
Polyacrylamide could be made into four series: no-ion, cation, anion, and mixed cation&anion.

Uses:
Polyacrylamide is an important water-soluble compound with flocculation properties, thickening, cut-resisting, block-reducing dispersing, etc.
Polyacrylamide properties vary with different derivative ions. So polyacrylamide is widely used in oil extraction, mining selection, coat washing, metallurgy, chemical, papermaking, sugar refining, pharmaceutical, environment protection, construction materials, and agriculture.
