NBR/modified montmorillonite and NR/HMMT nanocomposites were prepared by the mixing intercalation method with the monomers resorcin and hexamethylenetetramine complex . XRD and TEM showed that the interlayer spacing of HMMT had got much larger with RH addition and the layers of HMMT had dispersed in rubber matrix on nanometers. FTIR and crosslinking density results explained that chemical reaction had occurred between RH and rubber in the course of vulcanization, which improved the crosslinking density of rubber and enhanced the interaction between the rubber and HMMT.
