GENERAL DESCRIPTION
Vinyl: the univalent chemical radical H2C=CHCl-, derived from ethylene. It is a highly reactive, easily polymerizing, and low cost monomer used as basic materials for one of largest-selling plastic. In addition to its application of polymerization to make plastics with huge amount, vinly- is an functional group involved in cycloaddition, addition reactions, and carbon skeleton expansion reactions including Suzuki reaction, Heck reaction. This radical is useful in biomolecules chemistry such as protein sequencing and enzyme inhibitors. Some vinyl compounds impart characteristic flavors.

Vinyl isobutyl ether is a clear, flammable liquid with ether like odor; boiling at 83 C; insoluble in water; soluble alcohol, and ether. It may form unstable peroxides. This material is very hazardous when peroxide levels are concentrated by distillation or evaporation. It is used as a rocket fuel called hypergolic propellant. Vinyl ethers undergo homopolymerization via a cationic mechanism. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates, fumarates, and acrylics. It is an useful co-monomer for functional polymers. It is used as an intermediate to create a desired chemical compound through a series of chemical reactions in the field of pharmaceuticals, plastics dispersions, perfumery, lube oil and polyvinyl ether.
