| Abstract: |
| The sodium based montmorillonite/bio-based synthetic rubber poly(diisoamyl itaconate-co-isoprene) nanocomposites were prepared by latex co-coagulation method，and the chemical structure，microstructure， curing behavior，physical properties and air tightness of the nanocomposites were investigated.The results showed that the compatibility between poly(diisoamyl itaconate-co-isoprene) having polar ester groups and montmorillonite was good.When the addition level of montmorillonite was 5 phr，most of the montmorillonite in the nanocomposite was exfoliated.When the addition level of montmorillonite was over 10 phr，the nanocomposite had phase separated structure.As the addition level of montmorillonite increased，the modulus and tensile strength of the nanocomposites increased，and the air tightness was improved sharply at first and then became stable. |
