About Polychloroprene. Polychloroprene (a.k.a. Neoprene, Chloroprene Rubber) is the first synthetic rubber produced commercially by the free radical emulsion polymerization of chloroprene. It was first marketed by Dupont in 1933 under the DuPrene brand, and after significant improvements in the production process the brand was changed to Neoprene. Nowadays, it is one of the most important special rubbers produced, alongside butyl rubber, nitrile rubber (NBR) and ethylene propylene diene rubber (EPDM).
Chemical Formula. (C4H5Cl)n
Commercial Grades. General-purpose grade; crystallization resistant grade; adhesive grade; specialty grade; latex grade
Uses. Polychloroprene is a very versatile polymer thatexhibits an overall balance of interesting properties among synthetic rubbers. As a result, this polymer and its numerous grades are used in several applications: * General-purpose and specialty grades are most suitable for extrusion of molded parts. Specialty grade present improved mechanical performance due to the use of xanthogen disulfides as chain-transfer agent. * Crystallization resistant grades are commonly used to produce rubber articles that should retain their rubber properties even at very low temperatures. * Several glues and adhesives products make use of the rapid crystallization tendency of the adhesive grade polychloroprene. * Latex grades are used in the applications such as adhesives, binders, coatings, elasticizers and foams.
- Acetylene + hydrochloric acid (radical polymerization of chloroprene)
- Butadiene + chlorine (radical polymerization of chloroprene)
