Notes

“Neoprene or polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene.] Neoprene exhibits good chemical stability, and maintains flexibility over a wide temperature range. It is used in a wide variety of applications, such as laptop sleeves, orthopedic braces (wrist, knee, etc.), electrical insulation, liquid and sheet applied elastomeric membranes or flashings, and automotive fan belts.”

“Neoprene is produced by free-radical polymerization of 2-chlorobutadiene. In commercial production, this polymer is prepared by free radical emulsion polymerization.  Polymerization is initiated using potassium persulfate.  Bifunctional nucleophiles, metal oxides (e.g. zinc oxide), and thioureas are used to crosslink individual polymer strands.  Outside of Russia and China, about 300,000 tons of neoprene are produced annually”
