CAS No.:9003-01-4
Polyacrylic Acid (PAA)
Synonyms: Acrylic Homopolymer
Molecular formula: (C3H4O2)n
CAS NO.: 9003-01-4
Polyacrylic Acid is colorless, transparent or slightly yellow liquid. It can form stable compounds with metal ions, calcium, magnesium, etc., and has excellent decomposition effect on calcium carbonate and calcium hydroxide in water. The molecular weight of this product for water treatment is generally 2000-5000, and it is miscible with water, soluble in ethanol, isopropanol, etc. Weakly acidic. Polyacrylic acid is a low relative molecular weight acrylic monomer, and organic phosphonate, organic phosphonate, polyphosphate compound use, has a good synergistic effect, calcium phosphonate, iron oxide in water has excellent dispersion effect. Can be operated without fouling under alkaline and high concentration conditions.
Application
Polyacrylic acid is Colorless or pale yellow liquid. It can form stable compounds with metal ions, calcium, magnesium, etc.,
It is often used in combination with corrosion inhibitors and compound water stabilizers. Has a synergistic effect.
