Abstract :Synthesized $N$-insert ignore into journalissuearticles values(4-bromophenyl);-2-methacrylamide insert ignore into journalissuearticles values(BrPMAAm); and $N$-insert ignore into journalissuearticles values(4-fluorophenyl);-2-methacrylamide insert ignore into journalissuearticles values(FPMAAm); monomers were polymerized via free radical polymerization. Montmorillonite-containing raw clay insert ignore into journalissuearticles values(NaMT); was purified to obtain pristine clay insert ignore into journalissuearticles values(SMT);. XRF results of the SMT sample showed that sodium amount increased and so it is sodium montmorillonite. Using the SMT and organic surfactant hexadecyltrimethylammonium bromide insert ignore into journalissuearticles values(CTAB);, organoclay insert ignore into journalissuearticles values(OSMT); was synthesized. d$_{001}$ interlayer distances were 1.4967 nm and 2.0439 nm for SMT and OSMT, respectively. Composites of BrPMAAm and FPMAAm monomers were obtained using 2%, 4%, 6%, and 10% organoclay by in situ polymerization. Molecular weights for polyinsert ignore into journalissuearticles values(BrPMAAm);, polyinsert ignore into journalissuearticles values(BrPMAAm);-10%OSMT, polyinsert ignore into journalissuearticles values(FPMAAm);, and polyinsert ignore into journalissuearticles values(FPMAAm);-10%OSTM were 91,300, 31,300, 17,400, and 23,700, respectively. Thermal properties of the nanocomposite were also developed when compared to the pure homopolymer. The beginning thermal decomposition temperature of nanocomposites was shifted to higher temperature. An exfoliated structure was found for the nanocomposites.
