Abstract

‎(St-co-BA) polymer through montmorillonite (MMT) nanocomposite emulsion is prepared by ‎in situ intercalative emulsion polymerization of styrene (St), butyl acrylate (BA) in the ‎presence of organic modified montmorillonite (OMMT) with different OMMT contents (0, ‎‎0.5, 1.0, 1.5, and 2.0 wt%). The synthetic compounds are characterized by FTIR, XRD. The ‎nanocomposite emulsions are characterized by applying FTIR, SEM, TEM, TGA and DSC ‎techniques in order to investigate the structure and the thermal properties of the coplymer. ‎The properties of the nanocomposite emulsions containing OMMT are better than styrene-‎acrylate emulsion. The study of monomer conversion versus time and different OMMT ‎contents indicates that the polymerization rate is decreased by increasing the concentration of ‎styrene and OMMT. Consequently the properties of the nanocomposite emulsion containing 1 ‎wt % OMMT are better than other contents. ‎
