PAM(Polyacrylamide)

Polyacrylamide ,abbreviated as PAM ,is a glassy solid ,apt to sop up water ;the speed of sopping up water varies with different derivative ions .It is soluble in water and organic solvents in acetic acid ,glycol ,glycerin and amine .It will dissolve after long time heating .Dissolving temperature is over 120 .It carbonates to black power at 210 without oxygen .It could be made to four series ,e.g.,non-ion ,cation ,anion and mixed  cation & anion.

PAM is an important water-soluble compound with the properties of flocculation ,thickening ,cut-resisting ,etc.
