Basic Information

Structural Information

• Structure Type: Water-soluble anionic polymer, formed by radical polymerization of acrylic acid monomers.
• Structural Features: Long linear polymer chain with a large number of carboxyl groups on the molecular backbone. It possesses strong hydrophilicity, ion exchange capacity and thickening property. The molecular weight varies according to different polymerization degrees.

Physical & Chemical Properties

• Appearance: Colorless to pale yellow viscous liquid or white solid powder
• Odor: Slight characteristic odor
• Density: 1.05 ~ 1.20 g/mL (liquid form, 20 °C)
• pH Value (1% Aqueous Solution): 2.0 ~ 3.5
• Solubility: Fully soluble in water, methanol and ethanol; insoluble in hydrocarbons, esters and other non-polar organic solvents
• Viscosity: Varies greatly depending on molecular weight and concentration
• Stability: Stable under normal temperature. High temperature and strong alkali will cause molecular chain degradation. Avoid long-term exposure to strong oxidants.

Synthesis & Applications
