چکیده:

Poly styrene (PS) and poly methyl styrene (PMS) are two importantb thermoplastic materials. This polymers is widely used industry. Also polyaniline and its derivatives have high an tioxidative stability and are considered belong to the most useful conductive polymers. poly (styrene-co-methylstyrene) synthesied by nitroxide – mediated “living” free radical polymerization (NMRP). Then N-bromosuccinimide used as a brominating agent to obtain of copolymer with bromine. Then we have linked 1,4-phenylendiamine to this macro initiators. Polystyrene- grafted – polyaniline (PS-g- PAni)has been synthesized by adding solution of ammonium persulfate and p-toluenesulfonic acid in water. For synthesis of nanocomposites with montmorillonite (MMT) organophilic clay was synthesized by a cation exchang reaction between the clay and hexa decl trimethy ammonium chloride salt in deionized water by mechanical stirring over night. synthesis of nanocomposites carried out by solution intercalation methods. . The structure of obtained copolymers, therpolymers and all componens were investigated by 1HNMR, GPC, FT-IR, SEM and XRD spectroscopy.
