Copolymer of Maleic and Acylic Acid (MA/AA)
CAS No. 26677-99-6
Structural formula:
MA/AA is a low molecular weight polyelectrolyte, which is copolymerized by maleic acid and acrylic acid in a certain ratio. MA/AA has a strong dispersing effect on carbonates, etc., and has high thermal stability. It can be used under harsh conditions such as high te
mperature of 300℃. It has good compatibility and synergistic effect with other water treatment agents. It has a good inhibitory effect on the formation of scale including phosphate. Due to its excellent scale inhibition and high temperature resistance, MA/AA is widely used in low-pressure boilers, central heating, central air conditioning and various circulating cooling water systems. MA/AA can also be used as a chelating dispersant in the textile printing and dyeing industry.
| Item | Indicator | |
| Appearance | Brown-red transparent liquid | Light yellow to yellow transparent liquid |
| Solid content/% | ≥48.0 | ≥50.0 |
| pH(1%Aqueous solution) | 2.0～3.0 | 2.0～3.0 |
| Density(20℃)/g·cm-3 | ≥1.20 | ≥1.18 |

When used in combination with other organic phosphonates, the dosage is generally 2-10 mg/L.
The dosage of MA/AA as textile printing and dyeing auxiliary and detergent is determined by experiments.
MA/AA is acidic. Pay attention to labor protection during operation and avoid contact with skin, eyes, etc. Rinse with plenty of water after contact.
MA/AA is packed in plastic barrels, 25kg or 200kg per barrel. The storage period is 12 months.
