Knowledge of sodium polyacrylate

Abstract: Sodium polyacrylate is a kind of acrylic acid products with a wide range of uses, and its demand is increasing, so it is also a good variety for leather chemical plants. COONa sodium polyacrylate (—CH_2—CH——)n has powder (High molecular weight)and liquid (low molecular weight). The powder product is white, and the liquid product is a colorless transparent to light yellow viscous liquid. It is a water-soluble resin. It is easy to agglomerate at a pH of about 4 and is about 2.5. Soluble. It dissolves well in sodium hydroxide aqueous solution, but precipitates in aqueous solutions such as calcium hydroxide or magnesium hydroxide. Almost insoluble
