Description

Chloroprene, 2-chloro-1,3-butadiene, is a colorless, volatile synthetic liquid that has a pungent ether-like odor. Synthesis of chloroprene was first reported by chemists of the E. I. du Pont de Nemours Company in 1931 following studies of acetylene polymerization with the objective of producing synthetic rubber. The chloroprene monomer differs from isoprene, the fundamental monomer of natural rubber, only by substitution of chlorine for the methyl group of isoprene. Chloroprene was observed to polymerize much more quickly than did isoprene. In industrial processes prior to 1960, chloroprene was produced in relatively high yields by reacting vinyl acetylene with hydrogen chloride. Today, chloroprene is produced more efficiently by chlorination of 1,3-butadiene.
When compared with natural rubber the chloroprene synthetic polymer, polychloroprene, was noted to be much denser, more resistant to water and hydrocarbon solvents, less permeable to many gases, and was more resistant to degradation by oxygen, ozone, hydrogen chloride, hydrogen fluoride, and other chemicals. Due to desirable physical and chemical properties, polychloroprene and its latex polymers are produced in quantities exceeding 200 000 metric tons at a limited number of facilities around the world. Chloroprene production is closely tied to demand for polychloroprene.
