Description

General description

(Vinylbenzyl)trimethylammonium chloride is a quaternary ammonium salt commonly used as a monomer in polymerization reactions to produce unique polymers. Its vinylbenzyl group allows for easy radical polymerization and copolymerization, enabling incorporation into different polymer backbones like polyacrylates, polyvinyl acetates, and styrene-based polymers. These resulting polymers possess excellent cationic properties, making them suitable for applications such as water treatment, papermaking, textiles, coatings, flocculants, coagulants, dispersants, binders, adhesives, and modifiers.

Application

(Vinylbenzyl)trimethylammonium chloride (VBTA) can be used as a monomer:

• To synthesize the poly(AMA-DVB-VBTA) monolith columns, which are used for solid-phase microextraction in analytical chemistry.
• To prepare an anion exchange membrane for a lignin oxidizing electrolyzer. VBTA provides the anion exchange functionality to the copolymer membrane, which allows for the selective transport of anions across the membrane

It is also used to synthesize poly(VBTMAC) (homopolymer) and block copolymers for biomedical applications. For example, it can be used as a monomer to prepare:

• Poly[oligo(ethylene glycol) methacrylate]-b-based nanostructures for encapsulating magnetic nanoparticles and DNA.
• Nano-sized polyelectrolyte complexes.
• Homo and block copolymers of poly(VBTMAC) for non-viral DNA delivery systems.
