It is a water-soluble and linear organic polymer with high molecular  weight copolymerized by cation monomer and acrylamide. 

     As a flocculating agent,mainly used in industrial soild-liquid separation process,including settlement,clarification, concentrate and sludge dewatering processes etc.The main applications are urban metallurgical miner dressing,dyeing,sugar making and all kinds of industrial wastewater treatment.In paper industry,it can be used as dry strength agent,retention agent,and filter aid,which can greatly improve paper quality,save cost and improve the production capacity. In recent years ,it is also widely used  in oil field ,such as anti-clayswlling agent,acidification thickening agent,oil waste water treatment agent etc.
