Acrylamide-styrene copolymer

Acrylamide-styrene copolymer (CAS 24981-13-3), also referred to as styrene/acrylamide copolymer, is a synthetic polymer used across industrial processing sectors for rheology control, flocculation, and surface modification.

Its balance of hydrophilic and hydrophobic character makes it effective in both aqueous and mixed-phase systems where conventional homopolymers underperform. In water treatment, it functions as a flocculant to aggregate suspended solids.

This material improves clarification efficiency in municipal and industrial effluent streams by aggregating colloidal particles. Pulp and paper manufacturers apply it as a wet-strength or retention aid during sheet formation.

The polymer improves fiber bonding and filler retention, which is critical for high-quality paper production. In textile and leather processing, it modifies surface properties of substrates to improve coating adhesion.

Home care and industrial cleaning formulations use it as a rheology modifier to control viscosity. It ensures suspension stability in liquid detergent systems, preventing the separation of active ingredients during storage.

Acrylamide-styrene copolymer is supplied as an aqueous dispersion or solution, with dry powder forms available for applications requiring extended shelf life. Molecular weight and charge density vary by grade.

Suppliers typically offer technical-grade material tailored to specific processing conditions. Buyers should confirm solid content, ionic character, and viscosity specifications against their process requirements before procurement.
