Description and Uses
Vinyl chloride is a colorless, flammable gas
with a sweet ethereal odor. It is shipped as a
liquefied compressed gas. Contact of the liquid
with the skin can result in freezing or frostbite.
Vinyl chloride has been established as a human
carcinogen. In addition, acute effects of vinyl
chloride exposure include irritation of the skin
and eyes on contact. Inhalation of concentrations of more than 500 ppm produces mild anesthesia.
Anhydrous vinyl chloride does not corrode
metals at normal temperatures and pressures,
but in the presence of moisture and elevated
temperatures, vinyl chloride accelerates the corrosion of iron and steel at elevated temperatures.
Vinyl chloride polymerizes readily when exposed to air, sunlight, heat, or oxygen, although
it is chemically stable as shipped with an inhibitor (phenol).
Vinyl chloride is polymerized in various ways to polyvinyl chloride (PVC). It is also copolymerized with various other monomers to make a variety of useful resins.
