The sulfide polymers covered in this chapter are those based on the polysulfides derived from the reaction of dihalides and sodium di- or polysulfides polyphenylene sulfides generated from aryl dihalides and sodium sulfide polyalkylene sulfides generated from ethylene episulfide or dimercaptan-olefin or diolefin-diketone reactions, all of which are outlined in Scheme 1.

The acid-catalyzed polycondensation of certain mercaptoalcohols represents a method for the preparation of polyalkylene sulfides [87-90].

Polyalkylene sulfides (thioplastics) have a relatively high density (1.3-1.6 g/cm ) and usually have a strong odor of hydrogen sulfide or mercap-tans (like rotten eggs). The odor is especially strong on heating, and in this way they can be qualitatively identified.
