Layered silicate/natural rubber composites were prepared by direct polymer melt intercalation. Na-montmorillonite Kunipia-F and its organic derivates (organo-clays) prepared by ion exchange were used as clay fillers. Silica (SiO2)Ultrasil VN3, a filler commonly used in the rubber industry, was used in combination with clay fillers. The effect of clay or organo-clay loading from 1 up to 10 phr without (0 phr) or with silica (15 phr) showed significant improvement of the tensile properties (stress at break, strain at break and modulus M100). Modification of montmorillonite by three alkylammonium cations with the same length of alkylammonium chain (18 carbons) and different structure resulted in altered reinforcing and plasticizing effects of the filler in composites with rubber matrix.
