Abstract

On the basis of the x-ray diffraction (XRD) of poly(vinyl chloride) (PVC), the influence of component mixture sequences on the flexural strength of PVC/Poly(methyl methacrylate) (PMMA)/ nanoclay ternary composites was studied. Two component mixture patterns were investigated during the direct melting method PVC, including (a) an addition of PMMA granule then an addition of nanoclay, (b) a direct mixing of PVC and nanoclay then an addition of PMMA granule. The effect of the addition both nanoclay and PMMA granule on the PVC matrix was evaluated by differential thermal analysis (DTA) and field emission-scanning electron microscope (FE-SEM). The overall results indicated that with using the component mixture pattern which nanoclay is mixed to PVC compound at first time (second pattern), indicating the best result for flexural strength of ternary composites. Increasing the flexural strength of ternary composite with second pattern is about 4% higher than the ternary composite with first pattern.
