Neoprene® 2-chlorobutadiene

Chlorobutadiene or chloroprene rubbers (CRs), also called neoprene rubbers, are usually vulcanized by the action of metal oxides. The cross-linking agent is usually zinc oxide in combination with magnesium oxide [27]. CR can be vulcanized in the presence of zinc oxide alone, but magnesium... 

This is the preferred designation for all chloroprene polymers and copolymers. Chloroprene rubber was first introduced commercially in 1931 by DuPont and their trade name, originally DuPrene, later Neoprene, has almost become a generic term for all such rubber. See Chlorobutadiene. 

This is reacted with hydrogen chloride to produce chlorobutadiene (chloroprene) which is polymerised to polychloroprene. See Neoprene. Vinyl Chloride...

Chloroprene rubber, polychloroprene (CR). A syniheXic rubber produced by polymerization of chloroprene (2-chlorobutadiene, CH2=CCl—CH = CH 2). High weather and chemical resistance, better oil resistance than that of natural rubber products. Some applications building sheets, belts, cable insulations, technical rubber goods, contact adhesives. Trade names Baypren (FRG), Neoprene (USA). 

Chloroprene or Neoprene Rubber (CR). Chloroprene rubber (poly-2-chlorob-utadiene) is produced by the emulsion polymerization of 2-chlorobutadiene, in the presence of a free-radical initiator. Its general chemieal structure can be represented as... 

He also produced neoprene, a synthetic rubber, in 1931. He did so by treating viny-lacetylene with hydrochloric add. This produced the monomer chlorobutadiene which readily polymerizes to give the polymer neoprene. In the search to find artifical versions of silk and cellulose he used many types of condensation polymers. In 1935 he discovered the polyamide usually known as nylon by the condensation of adipic acid and hexamethylenediamine. Carothers suffered from depression and committed suidde in 1937. He therefore did not live to see the commercial production of nylon in 1940.
