| Abstract: | Linear low‐density polyethylene (LLDPE) is one of the most widely used polymers in many fields, but it is difficult to prepare LLDPE/clay nanocomposites because of the hydrophobic nature of LLDPE. In this study, the effectiveness of low molecular weight trimethoxysilyl‐modified polybutadiene (Organosilane) as a compatibilizer for LLDPE/clay nanocomposites was studied using X‐ray diffraction (XRD) and correlated with mechanical properties. Organosilane is known to react with dicumyl peroxide (DCP) to form free radicals, which react with LLDPE increasing the polarity of the LLDPE. Based on XRD and mechanical tests, it was concluded that Organosilane is a good compatibilizer for LLDPE and clay. Also when Organosilane was used in preparing LLDPE/clay nanocomposite foams, most mechanical properties were improved. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009 |
