| Abstract: | Three different organoclays (VDA-MMT, SDA-MMT, and 20A-MMT) originated from the same pristine clay (Na+-MMT) were used to prepare polyester-acrylate/clay nanocomposite films by in-situ ultraviolet (UV)-polymerization. Except for the commercial organoclay (20A-MMT), VDA-MMT and SDA-MMT were synthesized in this study by ion exchange method. The effects of different organoclays on the thermal stability, mechanical, and optical properties of the nanocomposite films were investigated. The physical properties of the nanocomposites were considerably different from each other because of the different characteristics of the organoclays. POLYM.
