1、 Application field
Acrylamide, whose molecular formula is CH2 = chconh2, is an unsaturated amide with two reactive active centers of amide group and double bond. It is the simplest and most important amide compound with active chemical properties. The main uses of acrylamide are as follows: synthesis of water-soluble polymers; Increase the adhesion of hydrophilic center of lipophilic polymer, softening point of resin and solvent resistance; It can also be used as a crosslinking agent for vinyl polymers. Among them, polyacrylamide polymers are one of the most widely used varieties of water-soluble polymers. They are known as "Baiye additives" and "universal products". They are mainly used in petroleum exploitation, metallurgy, construction, textile, sugar making, medicine, agriculture and other fields.
2、 Product characteristics
The molecular weight of acrylamide (AM) is 71.08, the concentration of aqueous solution is 25 ~ 50%, soluble in water, acetone, ethanol and slightly soluble in benzene. The nature of the dark place is relatively stable. It is easy to polymerize under high temperature or ultraviolet irradiation. It decomposes and emits corrosive gas when exposed to high heat. It belongs to category 6.1 poison and is harmful to the central nervous system.

4、 Method of use
Acrylamide polymerizes with acrylic acid (AA), sodium acrylate, 2-acrylamide-2-methylpropanesulfonic acid (AMPS) and other anionic intermediates containing active double bonds to form anionic polyacrylamide copolymer. Cationic polyacrylamide copolymer was synthesized with acryloyloxyethyl trimethylammonium chloride (DAC), methacryloyloxyethyl trimethylammonium chloride (DMC), dimethyl diallyl ammonium chloride (DMDAAC) and other active cationic monomers. Acrylamide can also synthesize non-ionic polyacrylamide by homopolymerization. Anionic polyacrylamide can be synthesized by subsequent alkali hydrolysis process. 5、 The packaging, storage and transportation packaging shall be sealed and shall not be in contact with air.
