Acrylic Sulphonated Polymers
Introduction
Acrylic Sulphonated Polymers (ASPs) are a class of synthetic water-soluble polymers derived from acrylic acid and sulfonic acid-based monomers. These polymers are widely used as dispersants, scale inhibitors, rheology modifiers, and water-reducing agents across various industries such as construction, water treatment, textiles, detergents, and oil & gas.
The presence of sulfonic groups (-SO₃H) in the polymer backbone enhances their thermal stability, solubility, and dispersing efficiency, making them suitable for demanding applications that require high-performance water management and dispersion control.
What Are Acrylic Sulphonated Polymers?
Acrylic sulphonated polymers are copolymers formed by the polymerization of acrylic acid, methacrylic acid, and sulfonic monomers such as 2-acrylamido-2-methylpropanesulfonic acid (AMPS). These polymers exhibit anionic functionality, which provides excellent water solubility and ionic compatibility.
They play a vital role in stabilizing suspensions, preventing particle agglomeration, and improving dispersion of solids in aqueous systems. Their chemical structure also provides resistance to high temperature, salinity, and pH variations, making them ideal for industrial…
