Definitions
- the present invention relates to polycarboxylate syntheses that are not harmful to the environment and comprising substituted groups such as sulfonate.
- the present invention comprises terpolymers obtained from acrylic acid, maleic acid and sodium vinyl sulfonate and used in the production of cleaning products.
- Detergents are chemicals having cleaning feature. Said products can be in the form of powder, liquid or cream. Many different chemicals are used in detergent manufacturing.
