WebChloroprene (2-chloro 1,3-butadiene), a conjugated non-hydrocarbon diolefm, is a liquid that boils at 59.2°C and while only slightly soluble in water it is soluble in alcohol. The main use of chloroprene is to polymerize it to neoprene rubber. [Pg.258] Polychloroprene is the oldest synthetic rubber. It is produced by the polymerization of 2 ... WebMar 13, 2007 · In the polymerization of perdeuterovinyl chloride an ethyl radical originating from AlCl(C2H5)2 was found to be incorporated into the polymer. Polymerization of chloroprene with the same catalyst in carbon tetrachloride was kinetically investigated, and a square-root dependence of the catalyst concentration on the rate was seen.
Chloroprene is the common name for 2-chlorobuta-1,3-diene (IUPAC name) with the chemical formula CH2=CCl−CH=CH2. Chloroprene is a colorless volatile liquid, almost exclusively used as a monomer for the production of the polymer polychloroprene, better known as neoprene, a type of synthetic … See more Although it may have been discovered earlier, chloroprene was largely developed by DuPont during the early 1930s, specifically with the formation of neoprene in mind. The chemists Elmer K. Bolton, Wallace Carothers See more It is in hazard class 3 (flammable liquid). Its UN number is 1991 and is in packing group 1. Hazards Chloroprene is toxic. It is reactive toward air, giving peroxides, which are also toxic. Handling of and … See more Chloroprene is produced in three steps from 1,3-butadiene: (i) chlorination, (ii) isomerization of part of the product stream, and (iii) dehydrochlorination of 3,4-dichlorobut-1-ene.
