property:
polyacrylamide, addreviated pam, is a glassy solid, apt to water absorbing. Pam is the speed of absorbing water varies with different derivative ions.
Pam could be made to four series: no-ion,cation,anion and mixed cation&anion.

usages:
pam is an important water-soluble compound with the properties of flocculation, thickening, cut-resisting, block-reducing dispersingetc. Pam properties vary with different derivative ions. So pam is widely used in the field of oil extraction, mining selection, coat washing, metallurgy, chemical, papermaking, sugarrefining, pharmaceutical, environment protection, construction materials and agriculture.
