This paper focused to the PVC composites with kaolinite. Poly(vinyl chloride) hybrids have been prepared by melt intercalation method using both natural and modified kaolinite. Kaolinite is the most common two-sheet type clay mineral. In this study kaolinite (SAK47) was modified with urea, (SAK47/urea), to expand the interlayer basal spacing. Next the intercalated/exfoliated kaolinite (del. SAK47) after washing of urea from kaolinite-urea intercalate was prepared. The interactions between kaolinite and urea were discussed by FTIR-ATR
