First, the physical properties of
The physical properties of polyacrylamide mainly determined by the behavior in aqueous solution, since the molecular chains containing amide groups
Or ion gene, so its distinguishing feature is highly hydrophilic, can be dissolved in water in various proportions, polyacrylamide
Aqueous electrolyte have a good tolerance, is not as sensitive ammonium chloride, sodium sulfate, etc., in a surfactant
It may also be compatible.
Second, the chemical reaction
Pendant polyacrylamide molecular chain is lively amide group, a variety of chemical reactions can occur can be obtained
We have a variety of derivatives, but the approach of gene effect, the reaction is often not entirely.
