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. ‎ UR - https://icc.journals.pnu.ac.ir/article_4234.html L1 - https://icc.journals.pnu.ac.ir/article_4234_73f9858c522e4ed8ec70859d4e6beaad.pdf ER -
