Vinylbenzyl chloride (VBC), also called chloromethyl styrene (CMS),a versatile building block that makes it easy to create your own special monomer and polymer systems.
it consists of a polymerizable double bond and a benzylic chloride group. The monomer is a mixture of meta (~57%) and para (~43%) isomers. Reactions can be carried out on the chloromethyl group before or after polymerization. The vinylbenzyl chloride can be reacted with primary, secondary, and tertiary amines, and many other nucleophiles.
Difficult application problems can be solved with VBC and a little imagination. While there is still much unexplored territory in the use of VBC, here are just a few of the ways it can be used.
1. VBC can be used to create polyelectrolytes with properties applicable to latex electrodeposition on metals. Other VBC-based polymers include polymeric surfactants, flocculating agents, phase transfer catalysts, electron carriers and viologens, ion exchange resins, and polymeric mordants for photographic dyes.
2. VBC can also make it easier to carry out reactions by acting as a polymeric support. After the molecular synthesis is completed, the modified molecule can be separated from the chloromethyl group. The polymeric support function of VBC can be used in peptide synthesis.
3. Used as a polymer reactant, the chloromethyl group of VBC can be modified by substitution of sulfinic acid, nicotinamide, tetrathiafulvalene, fluorinated ketone or amine, nadium derivatives, Bender’s salt, and many others in place of the chloride.
4. The chloride of the chloromethyl group of VBC can also be replaced by biochemical, light-absorbent compounds such as chlorophyll, hemin, porphyrin, and metalloporphyrin to create photosensitive polymers. Using thionine or benzopyran to replace the chloride creates a photochromic polymer. VBC can also be used to create photoconductive polymers.
5. VBC can be used for a number of analytical applications such as partial resolution of alpha-amino acids, noble metal extraction, uranium recovery, phenol complexing resins, sulfur dioxide removal, copper, cobalt, or mercury complexing, and separation of nucleosides.
6. VBC can be used to combine and improve the characteristics of elastomers such as improving scorch time, and increasing temperature and weather resistance. It can be used to inhibit elastomer decomposition and even to produce photocurable, water soluble elastomers.
Lets you attach functional groups before or after polymerization Vinylbenzyl chloride (VBC), also called chloromethyl styrene (CMS), consists of a polymerizable double bond and a benzylic chloride group. The monomer is a mixture of meta (~57%) and para (~43%) isomers. Reactions can be carried out on the chloromethyl group before or after polymerization. The vinylbenzyl chloride can be reacted with primary, secondary, and tertiary amines, and many other nucleophiles. The ability to perform reactions to make a new monomer before the polymerization of VBC has advantages. This allows you to control more precisely the characteristics of the desired polymerized product. By starting with VBC, many of the problems, costs, and hazards associated with chloromethylating styrene at your facility are eliminated.
The high purity of VBC from Mr Tek ltd allows high molecular weights to be attained with a minimum of undesirable cross-linking. VBC will copolymerize with a wide variety of monomers such as acrylic esters, styrene, acrylamides, and more. VBC gives you flexibility in polymerization VBC can be homopolymerized or copolymerized using solution, suspension, ionic, mass, emulsion, and other specialized techniques. This bifunctional monomer may be polymerized or chemically modified to achieve the desired product. VBC has been used to create products with a variety of structures such as films, beads, coatings, and many others.
