In crosslinked latex when insert of GMA then absorption property reduced when the solvent was nonpolar organic. Glass transition (Tg) temperature of composite was increased which enhanced the thermal stability of latex composite but in lower content of nanoclay, thermal stability decreased, probably due to changing the degree of exfoliation structure and forming the intercalated structure of nanoclay into the polymer, SEM and TEM of samples confirmed. Most acrylic acid is consumed in the form of the polymer.
