Surface treated absorbent polymers |
摘要 |
Surface treating water-absorbent resins with a polyquaternary amine substantially increases both the rate of water absorption and the quantity of water absorbed and retained by the resin. In addition to improved water absorbing properties, the surface-treated resins maintain the necessary "dry feel" required for most applications.
