The synthesis of neoprene involves the polymerization of chloroprene (2-chloro-1,3-butadiene) through a free-radical mechanism. This process typically occurs in an emulsion system, where the chloroprene monomer is emulsified in water with the aid of surfactants and then polymerized using free-radical initiators. The polymerization can be controlled to produce neoprene with specific properties, such as varying levels of hardness, chemical resistance, and elasticity.
