Neoprene

Neoprene also polychloroprene is a rank of synthetic rubbers that are provided by polymerization of chloroprene. Neoprene exhibits return chemical stability and maintained flexibility over the wide temperature range. Neoprene is sold either as solid rubber or in latex conduct to as well as is used in the wide shape of commercial applications, such(a) as laptop sleeves, orthopaedic braces wrist, knee, etc., electrical insulation, liquid together with sheet-applied elastomeric membranes or flashings, in addition to automotive fan belts.

Production

Neoprene is submission by free-radical polymerization of chloroprene. 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.
