Synthesis and Characterization of Magnetic Poly[St-co-CMS] Nanocomposites by ATRP Method

Polymer-based magnetic nanocomposites have gained an increasing attention because of theirpotential applications [1,2]. A variety of functional polymers such as polystyrene have beenused for the preparation of nanocomposites. This polymer is generally obtained via copolymerizationof styrene (St) and chloromethyl styrene (CMS) monomers by using one of thecontrolled radical polymerization methods such as atom transfer radical polymerization(ATRP) [3]. In this study some poly[St-co-CMS]/Fe3O4 nanocomposites in different St/CMSratios are synthesized through ATRP method starting from styrene/CMS monomers and magnetite-containing benzyl chloride initiator. In this rout, MNP s initially link to the polymerizationinitiator. The copolymers synthesized are thoroughly charecterised by Fourier transforminfraredspectroscopy (FT-IR), thermogravimetric analysis (TGA), field emission-scanningelectron microscopy (FE-SEM), X-ray diffraction (XRD), and vibrating sample magnetometry(VSM) techniques.
