Synthesis and Characterization of Poly(ethylene tetrasulfide)/layered Silicate (Clay) Nanocomposite by in situ Polymerization technique

Polymer-inorganic nanocomposites with a little percentage of layered silicates set in the polymer matrix are noteworthy because these nanocomposites usually give differentproperties[1]. In general, polysulfide polymers have good resistance against gases, ozone, organic solvent and air effects.This class of polymer has excellent resistance to a wide range of chemicals. The connection of a sulide linkage within polymer backbone imparts increased solvent resistance and other properties. These polymers are commercially synthesized by condensing an organic dihalide with sodiumpolysulfide. Previously, methylene dichloride and ethylene dichloride were exerted to prepare polysulfide polymers[2,3].
