Although Saran is a generic name for VDC copolymers in the United States, it is a Dow trademark in most foreign countries. Other trade names include Daran (Hampshire Chemical Corporation) and Serfene (Morton Chemical) in the United States, and Haloflex (Zeneca Resins), Diofan (BASE), Ixan (Solvay SA), and Polyidene (Scott-Bader) in Europe. The monomer is of particular economic interest because it is only 27 wt % hydrocarbon. In addition, B. E. Goodrich Chemicals (GEON) supply non-barrier VDC copolymers. 

Random copolymers of vinyl chloride and other monomers are important commercially. Most of these materials are produced by suspension or emulsion polymerization using free-radical initiators. Important producers for vinyl chloride—vinyUdene chloride copolymers include Borden, Inc. and Dow. These copolymers are used in specialized coatings appHcations because of their enhanced solubiUty and as extender resins in plastisols where rapid fusion is required (72). Another important class of materials are the vinyl chloride—vinyl acetate copolymers. Principal producers include Borden Chemicals Plastics, B. F. Goodrich Chemical, and Union Carbide. The copolymerization of vinyl chloride with vinyl acetate yields a material with improved processabihty compared with vinyl chloride homopolymer. However, the physical and chemical properties of the copolymers are different from those of the homopolymer PVC. Generally, as the vinyl acetate content increases, the resin solubiUty in ketone and ester solvents and its susceptibiUty to chemical attack increase, the resin viscosity and heat distortion temperature decrease, and the tensile strength and flexibiUty increase slightly. 

Several commercial products of PVC/TPU blends are available. The BF Goodrich Chemical Group has a PVC/ TPU blend based on their Estane series TPUs. For example, their Estane 54620, a polyester-based TPU with a °ShA 85 hardness, shows excellent compatibility with flexible PVC. The blends are produced by mixing PVC, TPU, plasticizer, stabilizer, and lubricant in a twin-screw extruder. These polymeric blends show intermediate mechanical properties between PVC and TPU.

Large-scale manufacture of butyl rubber started during World War II, in the scope of the U.S. Government rubber-procurement program, and the actual process is essentially similar to the historical one [9]. Bromi-nated butyl (BIIR) was introduced in the 1950s by Goodrich Chemical Co. [54-56] but substantial commercial development occurred only in 1971 when the Polysar Ltd continuous and economic manufacturing process based on elemental bromine came onstream [57]. Production of chlorinated butyl (CIIR) was introduced on a commercial scale by Exxon Chemical in 1961.
