This product is a water-soluble polymer material, completely dry polyacrylamide is a brittle white solid, easy to absorb water and retain water. Soluble in water, insoluble in methanol, ethanol, acetone, ether, aliphatic hydrocarbons and aromatic hydrocarbons. The active amide group on the polyacrylamide molecular chain can undergo hydrolysis, hydroxymethylation, sulfomethylation, amine methylation, Hofmann degradation and crosslinking reactions, through which a series of functional derivatives can be prepared. This product is white powder or fine sand, easily soluble in water, aqueous solution is weakly alkaline.
