What is Characteristic of Sodium Polyacrylate and its Uses?
Chemical Structure and Properties:
Sodium polyacrylate is derived from acrylic acid, a monomer that undergoes polymerization to form the polymer chain. The polymerization process involves linking the acrylic acid monomers, creating a long chain structure with sodium ions (Na+) attached. The remaining polymer is a white, granular powder that can retain large quantities of water, forming a gel-like substance. The chemical structure of sodium polyacrylate gives it the ability to absorb water and aqueous solutions through a process known as osmosis. The sodium ions within the polymer interact with water molecules, causing it to swell and trap water within its structure.
