polyacrylamide /PAM

usages:
1 as a coagulant in water treatment, flocculation, sludge dewatering agent.
2 for oil drilling in the precipitation agent, displacing agent
3 PAM also widely used in thickening, colloidal stability, drag reduction, bond, film, biomedical materials, etc.


physical properties:
The physical properties of polyacrylamide mainly depends on the behaviour in aqueous solution. Because of molecules chain gene containing amide groups or ions gene, the distinguishing feature is highly hydrophilic, and it can be dissolved in water in various proportions, and polyacrylamide aqueous solution on the electrolyte has a good tolerance, such as it is not sensitive with ammonium chloride, sodium sulfate, , and compatible.with surface active agents

Chemical reaction:
The pendant group of polyacrylamide chains is lively acylamino , chemical reactions can occur on a variety of derivatives can be obtained, but for the effect of neighboring genes, the reaction often can not be fully carried out.
