It was found that the reaction was a general one between aliphatic halogen compounds and water-soluble allaJine or Jkaline-earth polysulfides. Many different organic dihalides have been found to react with ium polysulfide to produce polymers. Commercially available dihalides include uthylene dichloride, propylene dichloride, dichloroethyl ether, tri ycol dichloride, and dichlorodiethyl formal. Dichlorodiethyl formal is the chief dihalide used in the polymers produced in the United States. It is made by the reaction of ethylene chlorohydrin with formaldehyde in the presence of an acidic catalyst ...

A good, less odoriferous, solvent resistant polymer, was obtained from dichlorodiethyl ether but the yield of this product was poor. The most successful reactant was dichlorodiethyl formal. 

The occurrence of cyclic structures also depends on the sulfur content of initial polysulfides the lower the sulfur content is, the more cyclic structures are formed. For this reason, to yield polysulfide polymers, the use of sodium tetrasulfide is preferred to sodium disulfide. More than 100 different monomers have been used [8-15], and based on experimental data, an attempt was made to establish reactivity-structure correlation. For halide derivatives, the most reactive are allylic and benzylic halide derivatives the primary derivatives are more active than the secondary or tertiary derivatives. As far as industrial monomers are concerned, 1,2-dichloroethane is more active than 2,2-dichloroethane or 2,2-dichlorodiethyl formal.

Various organic dihalides are employed in a reaction with sodium polysulfide to produce organic polysulfides (Thiokols). Ethylene dichloride, from the direct chlorination of ethylene, dichloroethyl formal, and /3,0 -dichlorodiethyl ether are the principal dihalides that have been employed in the process (44). These elastomeric polymers have been commercially available for a number of years, and many applications have been developed for them. They have excellent oil resistance and one of their principal uses has been in hose and tank linings in which that property is required.
