Poly(acrylic acid), powder [MW ~ 1,000,000]

Poly(acrylic acid) (PAA) is a high-molecular-weight polymer with carboxylic acid functional groups, making it highly hydrophilic and pH-responsive. It exhibits excellent water retention, viscosity modification, and film-forming properties, making it useful in applications ranging from hydrogels to coatings and dispersants.

Applications:

Superabsorbent Polymers: Used in hygiene products, agricultural water retention, and biomedical hydrogels.
Rheology Modifiers: Enhances viscosity in personal care products, adhesives, and coatings.
Water Treatment & Dispersants: Functions as a scale inhibitor and stabilizer in industrial formulations.
