Application Areas
At a suitable low concentration, the polyacrylamide solution can be regarded as a network structure, which is formed by mechanical entanglement and hydrogen bond between chains. At higher concentrations, PAM solutions are gelatinous because they contain many chain-by-chain contact points. PAM aqueous solution has good compatibility with many organic compounds that are mutually soluble with water, and has good compatibility with electrolytes. It is insensitive to ammonium chloride, calcium sulfate, copper sulfate, potassium hydroxide, sodium carbonate, sodium borate, sodium nitrate, sodium phosphate, sodium sulfate, zinc chloride, boric acid and phosphoric acid.
Polyacrylamide is a white powder or small particle with a density of 1.302g/cm3 (23℃), a vitrification temperature of 153℃, and a softening temperature of 210℃ [1]. The general method contains a small amount of water when drying, and will quickly absorb water from the environment when drying. The homopolymer separated by freeze-drying method is a white soft amorphous solid. But when precipitated from the solution and drying is vitreous partially transparent solid, PAM is completely dry PAM brittleness white solid, commodity polyacrylamide is usually under the condition of moderate dry, average moisture content is 5% ~ 15%, casting preparation of polymer film on the glass, are transparent, hard, brittle solid.

In anoxic condition, heat to 210℃ due to water loss weight; Further heating to 210~300℃ amide group decomposition into ammonia and water; When the temperature rises to 500℃, the formation of 40% of the original weight of the black sheet
