5. Production of polyvinyl chloride (PVC) and calcium carbide process Polyvinyl chloride (PVC) is produced using calcium carbide (CaC2) and acetylene (C2H2) in water to synthesize vinyl chloride monomer (CH2CHCl) And then through the polymerization of vinyl chloride to generate polyvinyl chloride - [CH CHCI] n- chemical reaction method.
