Description

Poly(Vinylbenzyl Trimethyl Ammonium Chloride) is a water-soluble, cationic polyelectrolyte featuring a quaternary ammonium functional group. This polymer is valued for its strong positive charge density and ability to interact with negatively charged surfaces and molecules. It is a critical material for industries requiring advanced flocculation, charge modification, or antimicrobial activity. The compound is identified by CAS No. 9017-80-5.

Application

• Water Treatment: Acts as a highly effective cationic flocculant for clarifying process water and wastewater by neutralizing and agglomerating suspended solids and organic matter.
• Paper Manufacturing: Used as a retention and drainage aid, as well as a dry strength agent, to improve paper quality and production efficiency.
• Textile Industry: Serves as a dye-fixing agent and antistatic agent, enhancing color fastness and processability of synthetic and natural fibers.
• Personal Care & Cosmetics: Functions as a conditioning agent and viscosity modifier in hair care and skincare formulations due to its substantivity to keratin.
• Biotechnology & Pharmaceuticals: Employed in chromatography as an anion exchange resin and in the formulation of some antimicrobial coatings.
• Oil & Gas Industry: Utilized as a clay stabilizer and shale inhibitor in drilling mud formulations to control formation damage.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
