【Application】
1.Used in the synthesis of silicone compounds.
2.Methacryloyloxyethyl trimethylammonium chloride is widely used in the production of flocculants, antistatic coatings, papermaking aids, oilfield chemicals, fiber auxiliaries, and other fine chemical products for the synthesis of silicone compounds.
3.Used for photometric determination of gold, cerium, free chlorine; used for the determination of nitrate, Mn, nitrite, chromates, copper salts, cobalt, mercury, and cyanide ions in air.
Methacryloyloxyethyl trimethylammonium chloride (commonly abbreviated as DMC or MADQUAT) is an important cationic functional monomer. Its molecular structure includes both a polymerizable vinyl group (-C=C-) and a positively charged quaternary ammonium group (-N+(CH₃)₃Cl⁻). This combination gives it excellent reactivity and water solubility, making it widely applicable across various fields:
1. Polymer Material Synthesis (Primary Application)
Cationic Polymer Production: Used as a comonomer with acrylamide (AM) and acrylic acid (AA) to produce cationic polyacrylamides (CPAM) and other polymers. These polymers, due to the positive charge groups on their chains, can electrostatically adsorb onto negatively charged substances such as colloidal particles, organic matter, and cells. They are extensively used in water treatment coagulants (removing suspended solids, COD, heavy metal ions from wastewater), papermaking retention and drainage aids (improving the retention rate of pulp fibers and fillers), and mineral flotation agents (enhancing the hydrophobicity of mineral surfaces).
Functional Polymer Materials: Used to synthesize polymers with special properties, such as antistatic materials (the conductivity of quaternary ammonium groups reduces surface resistance), antimicrobial materials (positive charges disrupt bacterial cell membranes, used in medical device coatings and food packaging), and ion exchange resins (quaternary ammonium groups exchange anions, used in water treatment or substance separation).
2. Personal Care and Cosmetics
Conditioners and Thickeners: Co-polymerized with other monomers (such as acrylic esters) to form cationic polymers, which are added to shampoos, conditioners, and skincare products. They improve hair smoothness, reduce static, or increase product viscosity and stability (e.g., polyquaternium-10, a common cationic conditioning agent).
3. Biomedical Field
Biomedical Materials: Utilizing its cationic properties and biocompatibility, it is used to synthesize cell culture scaffolds, drug carriers, or gene delivery materials (electrostatically binding DNA/RNA to assist in gene transfection).
Antibacterial Coatings: Grafting polymers containing DMC onto the surfaces of medical catheters and surgical instruments to inhibit bacterial adhesion and biofilm formation through the antibacterial activity of quaternary ammonium groups, reducing infection risks.
4. Textile and Dyeing Industry
Textile Finishing Agents: Through polymerization or grafting reactions, DMC is introduced onto fabric surfaces to impart properties such as wrinkle resistance, antistatic, and antibacterial functions, or to enhance dye fixation rates on fibers (improving dye fastness).
5. Other Fields
Oilfield Chemistry: Used as a monomer for drilling fluid additives or oil extraction polymers to improve the stability of drilling fluids or enhance permeability of oil-water wells through polymer adsorption (profile control and water blocking).
Coatings and Adhesives: Used to modify coatings or adhesives to improve their adhesion to substrates, water resistance, or corrosion resistance (e.g., synthesis of cationic resins for metal surface anticorrosive coatings).
Summary
The core value of DMC lies in its molecular structure, which includes both a polymerizable double bond and a cationic quaternary ammonium group, making it a key monomer for synthesizing functional high-performance polymers, especially significant in water treatment, personal care, and biomedical fields. It serves as a crucial bridge connecting basic chemical industries with advanced functional materials.
