Abstract

 The preparation of ethylene propylene diene terpolymer (EPDM)/organoclay NANOCOMPOSITEs by MELT BLENDING method was studied. The maleic anhydride modified EPDM oligomer (EPDM-MA) was used as a compatiblizer. The effect of ORGANOCLAY on structure of NANOCOMPOSITEs was evaluated by X-ray diffraction (XRD). The absence of basal plane peak in XRD results suggests that the EPDM-clay nanocomposits are exfoliated. The mechanical and thermal properties of NANOCOMPOSITEs were examined to observe the influence of the ORGANOCLAY on the physical properties. The results show remarkable improvement relative to that of EPDM without clay. To prepare EPDM-clay NANOCOMPOSITEs by a straightforward method, a second process was implemented. It was found that the properties of NANOCOMPOSITEs prepared by both methods is nearly the same; however the second method has lower cost and is industrially more practical.
