<unk>  is a chemical intermediate, not a final product. Due to the hazardous nature of<unk>  to human health there are no end products that use<unk>  in its monomer form. Polyvinyl<unk>  (PVC) is very stable, storable, and nowhere near as acutely toxic as the<unk>  monomer <unk> M).<unk>  liquid is fed to polymerization reactors where it is converted from a monomeric<unk> M to a polymeric PVC. The final product of the polymerization process is PVC in either a flake or pellet form. From its flake or pellet form PVC is sold to companies that heat and mold the PVC into end products such as PVC pipe and bottles. Several million tons of PVC are sold on the global market each year. Until 1974,<unk>  was used in aerosol spray propellant.<unk>  was briefly used as an inhalational anaesthetic, in a similar vein to ethyl<unk> , though its toxicity forced this practice to be abandoned. Smaller amounts of<unk>  are used in furniture and automobile upholstery, wall coverings, housewares, and automotive parts.<unk>  has also been used in the past as a refrigerant.
